In high-cavitation thin-wall food packaging lines running hot-runner tools with wall sections between 0.35 mm and 0.80 mm, TATREN PP Homopolymer HG 10 07 is processed at a melt temperature of 230–250 °C and a mould temperature of 15–35 °C. The melt flow rate of 10 g/10 min, determined according to ISO 1133-1:2022, is the primary control variable for achieving complete filling without excessive internal stress or warpage after demoulding. In this sector the polymer is fed as virgin HG 10 07 at 97–100 wt% of the total polymer stream, with a polyolefin-compatible colour masterbatch let-down of 0–3 wt%; where stack denesting or high-speed packing requires slip modification, erucamide-based masterbatch is introduced at 1–2 wt%, and nucleating agents, when specified, are limited to 0.05–0.20 wt% because over-nucleation of homopolymer PP reduces impact resistance at chilled mould walls and increases brittleness in frozen-food service conditions. The downstream production process uses high-speed hydraulic or all-electric injection moulding machines with clamp forces from 2,000 kN to 8,000 kN, screw L/D ratios between 20:1 and 25:1, valve-gated hot runners, and injection linear velocities of 200–400 mm/s, producing cycle times of 3–6 s in multi-cavity tools. Compliance is anchored to EU No 10/2011 with an overall migration limit of 10 mg/dm² for plastic food contact materials, FDA 21 CFR 177.1520 for polyolefin food contact, GB 4806.7-2016 for Chinese market access, and REACH Regulation (EC) No 1907/2006 for EU substance registration. Terminal finished products include dairy cups, margarine tubs, deli containers, frozen dessert tubs, and thin-wall food service containers used in cold and room-temperature filling lines.
Closure production using HG 10 07 shifts the main process limitation from melt plastication to gate freeze time and demoulding torque in high-cavitation tools. The resin’s narrow molecular weight distribution and 10 g/10 min MFR per ISO 1133-1:2022 permit stable filling of 48- to 96-cavity hot-runner tools with cycle times of 4–8 s, but gate freeze must be confirmed by short-shot seal studies because premature holding pressure release creates sink marks on the cap top face and increases ovality beyond the accepted ±0.15 mm diameter tolerance. The formulation for carbonated soft drink and still beverage caps uses HG 10 07 at 97–99 wt%, a slip masterbatch containing erucamide or oleamide at 0.5–1.5 wt%, and a colour masterbatch at 0.5–2 wt%; if the closure is intended for aseptic filling lines, the peroxide level in the masterbatch must be declared because residual peroxide affects organoleptic panel results. Production equipment generally includes high-speed accumulator-assisted injection moulding machines with clamp force from 1,800 kN to 5,000 kN, injection compression or sequential valve-gate control, and moulds with conformal cooling or high-turbulence water circuits operating at 10–20 °C to stabilise cap skirt thickness and thread definition. The applicable compliance framework includes EU No 10/2011 for food contact migration, FDA 21 CFR 177.1520, REACH Regulation (EC) No 1907/2006, and where child-resistant closures are required, ISO 8317:2015; migration testing must be performed on the finished closure with liners or gaskets included, not on the resin alone. Terminal finished products include single-piece screw caps for PET and HDPE bottles, sports caps, tamper-evident closures, and still-water closures.
For washing machine outer tub covers, control panel frames, and dishwasher cutlery basket brackets, the moisture regain of TATREN PP Homopolymer HG 10 07 in closed original packaging is sufficiently low that pre-drying is unnecessary at ambient relative humidity below 60%; however, when sacks are stored in unheated warehouses or opened for more than 8 h at relative humidity above 75%, hopper drying at 80 °C for 2–4 h prevents silver streaks on textured surfaces. In this sector the formulation is typically 96–100 wt% HG 10 07 with a colour masterbatch at 2–4 wt% and, where dust attraction on white components is undesirable, an antistatic masterbatch at 1–3 wt%; flame-retardant masterbatches are technically possible but they alter the UL 94 classification and must be qualified separately on the finished part. The downstream production process is conventional injection moulding on machines with clamp force from 1,500 kN to 6,000 kN, screw L/D ratios of 20:1–25:1, melt temperatures of 220–250 °C, and mould temperatures of 20–40 °C; holding pressure is maintained until gate freeze, typically 1.5–3 s per 1 mm of nominal wall thickness, to reduce sink marks over bosses and ribs. Compliance for white goods parts is primarily electrical safety under IEC 60335-1:2020, flammability classification under UL 94 HB, and material-level restrictions under RoHS Directive 2011/65/EU and REACH Regulation (EC) No 1907/2006; full appliance certification is completed on the finished device, not on the raw material. Terminal finished products include machine housing brackets, ventilation grilles, detergent drawer fronts, tub cover rings, and sensor mounting plates.
Specifying HG 10 07 in low-load underhood structures such as fan shroud support brackets, washer fluid reservoir brackets, and battery tray side covers requires explicit evaluation of low-temperature impact because the notched Charpy impact strength of homopolymer PP at -20 °C is below that of ethylene-propylene block copolymers. Designs transitioning from talc-filled copolymer to HG 10 07 must increase corner radii to at least 0.5 mm and avoid weld lines in direct fan or bracket load paths; otherwise, brittle failure can occur during cold-temperature installation or vibration. Where stiffness above 1,500 MPa is required, the grade is used as the base resin in a talc-filled compound at 70–80 wt% HG 10 07 with 20–30 wt% talc masterbatch or surface-treated talc filler; where the part is unfilled, HG 10 07 is used at 98–100 wt% with a heat stabilisation masterbatch at 0.2–0.5 wt% for sustained hot air exposure. Downstream processing for talc-filled variants begins with twin-screw compounding on a co-rotating extruder with L/D ratio of 40:1, barrel temperatures from 190 °C to 230 °C, and vacuum devolatilisation at -0.08 MPa to remove moisture from talc; the compound is then injection moulded at melt temperatures of 210–240 °C and mould temperatures of 30–60 °C, with post-mould dimensional checks after 24 h conditioning. Compliance is governed by IATF 16949:2016 for automotive quality management, REACH Regulation (EC) No 1907/2006 for substance registration, Directive 2000/53/EC on end-of-life vehicles for heavy metal restrictions, and specific OEM material specifications that typically require heat ageing per ISO 188 and tensile properties per ISO 527-2:2012. Terminal finished products include fan shroud brackets, cable troughs, air intake covers, battery tray side panels, and low-load reservoir brackets.
Industrial logistics moulders use HG 10 07 for returnable transport packaging where rigidity, cleanability, and chemical resistance to dilute acids, alkalis, and hydrocarbon-free detergents are required. The homopolymer grade is formulated at 96–98 wt% with a UV stabiliser masterbatch at 2–4 wt% for outdoor storage and a colour masterbatch at 0–2 wt%, while antistatic or conductive carbon black masterbatches are generally avoided because they lower tensile strength and complicate regrind streams. The production process for pails and crates uses large injection moulding machines with clamp force from 8,000 kN to 25,000 kN, melt temperatures of 210–240 °C, mould temperatures of 15–30 °C, and injection pressures sufficient to fill thick walls from 2 mm to 6 mm; cycle times range from 20 s for shallow crates to 45 s for pails with thick bottom rims, and in-mould labelling is applied where high-quality print is required. Compliance for industrial packaging includes REACH Regulation (EC) No 1907/2006, RoHS Directive 2011/65/EU for restricted substances in reusable articles, and, when used for dangerous goods, the UN performance requirements for plastics packaging under ADR/RID/IMDG with drop and stacking tests on the finished pail, not on the raw material; food contact is not implied unless the finished article is tested under EU No 10/2011 or FDA 21 CFR 177.1520. Terminal finished products include stackable distribution crates, agricultural picking bins, pails with lids, collapsible storage boxes, and industrial tote boxes.
Where diagnostic consumables are injection moulded from HG 10 07, the resin is not supplied with pharmacopoeial certification, and responsibility for biocompatibility lies with the final article manufacturer. The material is employed in laboratory and diagnostic disposables at 99–100 wt% with a processing stabiliser masterbatch at 0–0.5 wt%; slip agents are excluded where they interfere with subsequent surface treatment, reagent coating, or optical inspection. Downstream processing uses micro-moulding or high-speed injection machines with melt temperatures of 200–230 °C, mould temperatures of 15–30 °C, hot-runner or direct cold-runner gating, and cycle times of 8–15 s for thin-wall items; for cleanroom production, the moulding cell is operated under ISO 14644-1 Class 8 conditions with filtered pellet handling. Compliance for finished laboratory ware may involve ISO 13485:2016 quality management, ISO 10993-1:2018 biological evaluation, REACH Regulation (EC) No 1907/2006, and RoHS Directive 2011/65/EU; however, raw HG 10 07 lot release does not replace end-product validation. Terminal finished products include pipette tip racks, test tube racks, specimen containers, Petri dish adapters, and non-sterile laboratory transport boxes.

TATREN PP Homopolymer HG 10 07 is supplied as a natural, general-purpose injection-moulding grade of isotactic polypropylene. The material is distinguished from random copolymers by the absence of ethylene comonomer in the polymer backbone, which raises crystallinity and produces a higher modulus and upper service temperature at the expense of low-temperature impact resistance. Published manufacturer data list a nominal melt mass-flow rate of 10 g/10 min when measured at 230 °C under a 2.16 kg load according to ISO 1133-1:2022. Typical mechanical values include a tensile modulus of 1500 MPa and a notched Charpy impact strength of 2.0 kJ/m² at 23 °C. The product is employed in thin-wall food packaging, caps and closures, housewares, and technical mouldings where stiffness and short cycle time are primary requirements. The medium-flow position also separates it from lower-flow homopolymers used in thick-wall pipe and sheet extrusion.
The homopolymer chain consists primarily of repeating propylene units with high isotacticity; this stereoregularity permits lamellar crystallisation and the formation of spherulitic morphology during cooling. The density is typically 0.905 g/cm³ when measured by ISO 1183-1. In differential scanning calorimetry, an isotactic polypropylene homopolymer of this class shows a melting endotherm peak in the range 160–166 °C under ISO 11357-3; the crystallisation exotherm during cooling at 10 K/min commonly appears between 115 °C and 120 °C. Because no ethylene comonomer is present, the crystalline fraction is higher than that of random copolymer grades, which directly raises tensile modulus, Vicat softening temperature, and shrinkage anisotropy. Table 1 summarises representative physical and mechanical values obtained from current manufacturer literature. The values must not be read as specification limits; batch-specific values are controlled in the certificate of analysis and can vary within the manufacturing tolerance.
| Property | Unit | Test method | Typical value |
|---|---|---|---|
| Melt mass-flow rate | g/10 min | ISO 1133-1:2022 | 10 |
| Density | g/cm³ | ISO 1183-1 | 0.905 |
| Tensile modulus | MPa | ISO 527-2 | 1500 |
| Tensile stress at yield | MPa | ISO 527-2 | 35 |
| Tensile strain at yield | % | ISO 527-2 | 8 |
| Charpy notched impact strength at 23 °C | kJ/m² | ISO 179-1/1eA | 2.0 |
| Vicat softening temperature A50 | °C | ISO 306/A50 | 154 |
| Heat deflection temperature B | °C | ISO 75-2/B | 95 |
The notched Charpy value of 2.0 kJ/m² at 23 °C under ISO 179-1/1eA indicates a brittle-to-ductile transition sensitivity below room temperature. Thus the grade is not intended for sub-zero impact applications unless a suitable copolymer or impact-modified compound is selected. For applications requiring prolonged heat exposure above 100 °C, oxidative stability should be confirmed by oven-ageing or oxidation induction time measurements under ISO 11357-6, because the base stabilisation package is designed for standard injection-moulding thermal history rather than long-term hot-service exposure.
The nominal melt mass-flow rate of 10 g/10 min is measured at low shear in a capillary die; it provides a comparative index of average molecular weight but does not replace high-shear rheometry. The ISO 1133-1:2022 method uses a die of 2.095 mm diameter and 8.000 mm length, so the apparent shear rates generated in the measurement are orders of magnitude lower than those in gate regions. In injection moulding, the material is subjected to apparent shear rates that can exceed 10,000 s⁻¹ through gates and thin walls. Under those conditions, shear thinning lowers apparent viscosity, and the relative flow advantage of a 10 g/10 min grade over a 2–4 g/10 min grade becomes most visible in fill pressure and clamp force reduction. A general-purpose injection screw with an L/D ratio of 20:1 to 24:1 and compression ratio of 2.5:1 to 3.5:1 is adequate for plastication. Process temperatures used in production equipment are summarised in Table 2; nozzle and melt temperature should be verified with a needle pyrometer rather than relying solely on barrel set points. Published data for spiral-flow length of this specific grade are limited; converter trials remain necessary when tool dimensions approach the flow limit.

| Barrel compression zone | °C | 220–250 |

| Nozzle | °C | 230–260 |
| Mould temperature | °C | 20–50 |

Pre-drying is not required for pellets stored in dry indoor conditions. When silo, gaylord, or hopper storage has exposed the pellets to relative humidity above 60%, surface moisture can generate splay, flow marks, and bubbles in the moulded part. Drying in a dehumidified-air dryer at 80 °C for 2–3 h is typically sufficient. Melt temperature above 270 °C or residence time beyond 15 min in a stagnant melt pool can initiate thermo-oxidative chain scission, shift the MFR upward, and produce yellowing. The stabilisation package does not eliminate the need for careful purging when shutting down a heated barrel; a lower-MFR polypropylene purging grade or a commercial purge compound should be used to remove degraded polymer from dead spots in the screw, check ring, and hot runner manifold.
Thin-wall packaging and container applications are the most demanding use for the 10 g/10 min homopolymer because reduced wall thickness simultaneously increases flow resistance, shortens gate freeze-off time, and amplifies the visual effect of shrinkage. Moulding shrinkage in polypropylene homopolymer is anisotropic; values determined on 60 mm × 60 mm × 2 mm plaques under ISO 294-4 commonly fall between 1.0% and 2.5% in the flow and transverse directions. Warpage arises when differential shrinkage between flow-oriented and transverse-oriented regions is frozen into the part by rapid cooling. For flat lids and trays, a minimum draft angle of 0.5° to 1° is required for ejection, but dimensional flatness is controlled by uniform mould temperature, balanced gate locations, and sufficient packing time rather than by draft alone.
Weld lines represent a processing boundary for this grade because the notched Charpy impact of 2.0 kJ/m² is already limited at room temperature; the strength of a weld line can be lower than the bulk value, especially when the melt front temperature approaches the no-flow temperature. Multi-gate layouts and openings in container bottoms should be positioned away from tensile load paths. Production-scale experience on cold-runner multi-cavity tools shows cavity-to-cavity fill imbalance when the holding pressure is restricted by the machine hydraulic limit; the result is mass variation in caps and closures and intermittent dimensional failure in leak tests. The standard corrective sequence is to balance runner and gate dimensions, verify check-ring function, and then raise pack pressure within the machine’s allowable range. Pack pressure is generally set at 60–80% of the peak injection pressure for unfilled PP homopolymer, although the exact value depends on gate size and wall thickness. A high-flow grade does not eliminate sink marks; it only reduces the injection pressure needed to fill the cavity. Shrinkage compensation still depends on holding pressure and seal of the cushion.
Post-mould crystallisation continues after ejection. Dimensional measurement immediately after demoulding will differ from values obtained after 24–48 h under standard conditioning at 23 °C and 50% relative humidity according to ISO 291. Parts intended for tight assembly should therefore be measured after conditioning, and the shrinkage data used for tool cutting should include post-mould ageing. Mould temperatures of 20–50 °C permit cycle times set by cooling requirements; higher mould temperatures up to 70 °C improve surface gloss but increase demould time.
The principal difference between TATREN PP Homopolymer HG 10 07 and a random copolymer of equivalent flow is the absence of ethylene comonomer. Random copolymers typically exhibit tensile modulus from 900 MPa to 1200 MPa, Vicat softening temperatures from 120 °C to 135 °C, and notched Charpy impact values from 6 kJ/m² to 10 kJ/m² at 23 °C. The homopolymer, with a tensile modulus near 1500 MPa and Vicat softening temperature near 154 °C, is therefore selected for stiffness- or heat-dominated parts, while the copolymer is selected for impact-dominated or transparent applications. The optical difference is equally significant: homopolymer spherulites scatter light and produce higher haze than random copolymer grades, which are often clarified to meet see-through packaging requirements.
Against lower-flow homopolymers with MFR in the 2–4 g/10 min range, the 10 g/10 min grade reduces fill pressure and allows a shorter packing phase but sacrifices molecular weight-dependent properties such as impact strength, melt strength, and resistance to slow crack growth under load. This trade-off becomes visible in deep containers and large flat parts, where lower-flow grades produce fewer sink marks and more uniform wall thickness but require higher clamp force and longer cycles. Against very high-flow homopolymers with MFR above 25 g/10 min, HG 10 07 retains better weld-line strength and stiffness but is less suited to extremely thin sections below 0.5 mm or very long flow paths. Selection between these grades should be based on spiral-flow trials using the production mould’s gate design, not solely on the low-shear MFR value.
Food-contact status is not an intrinsic property of the pellet; it arises from the full formulation and the conversion history. The base homopolymer may be evaluated for compliance with Commission Regulation (EU) 10/2011 and FDA 21 CFR 177.1520 for olefin polymers, but the final article must undergo overall migration testing and, where relevant, specific migration testing on the exact colourant and masterbatch system used. The natural grade is typically formulated without heavy-metal-based pigments; nevertheless, RoHS 2011/65/EU compliance must be verified on the final coloured compound because external masterbatches can introduce restricted substances. For outdoor exposure, the stabilisation package is not intended for prolonged ultraviolet service; formulations intended for outdoor use require additional UV stabilisation and should be validated through artificial weathering under ISO 4892-2 or natural exposure according to ISO 877. Addition of filler or pigment masterbatches alters the melt viscosity and mechanical behaviour; the nominal 10 g/10 min MFR cannot be assumed for a let-down compound. The compounder should re-test under ISO 1133-1:2022 before tool transfer.
