Seculene PPR 1240 TV30 S0 is a 30 wt% talc-reinforced polypropylene random copolymer compound converted into automotive interior structural carriers on injection moulding lines with hydraulic clamp force from 12,000 kN to 30,000 kN, sequential valve-gated hot-runner manifolds, and accumulator-assisted injection to prevent flow hesitation at rib intersections. This talc-reinforced compound is not a substitute for unfilled PP-R pipe resin in pressure piping systems because mineral platelet alignment reduces long-term hydrostatic strength; applications are therefore limited to injection-moulded rigid components. The compound is charged at 100 phr in ready-to-mould form; black and charcoal colour masterbatch is limited to 1.5–2.5 wt% because heavier masterbatch additions reduce the effective talc fraction below 29 wt% and measurably lower the notched Charpy impact according to ISO 179-1:2023. Lot acceptance for this application includes MFR determination under ISO 1133-1:2022 at 230°C and 2.16 kg, flexural modulus under ISO 178:2019, and VOC emission classification under VDA 278 alongside VDA 277 and DIN 75201 for interior air quality. OEM cockpit programmes typically require flammability documentation to ISO 3795, heavy-metal compliance to the ELV Directive 2000/53/EC, and REACH SVHC disclosure. Melt temperature at the nozzle is constrained to 210–235°C, and the mould surface is maintained at 30–45°C; this range keeps talc platelets oriented in the flow direction without freezing high skin stress that causes lateral warpage after demoulding. Toolmakers observe that reducing mould temperature below 20°C to accelerate cycle time produces post-mould warpage of 3–6 mm across a 1,100 mm instrument panel carrier, while raising it above 60°C extends cooling time beyond 35 s without improving flatness. Holding pressure is maintained at 40–55 MPa until gate freeze is confirmed by part weight stabilisation; early decompression permits melt backflow from thick bosses and creates visible sink marks opposite the gate. Published data for this specific grade under paint-line thermal cycling is limited, so pre-production trials are used to establish dimensional compensation. Finished parts include instrument panel carriers, door module carriers, centre console substrates, and glove box structural shells for passenger vehicles requiring low-gloss, low-warpage interior components.
In horizontal-axis washing machine tubs and dryer base frames, Seculene PPR 1240 TV30 S0 is processed at 100 phr with detergent-stable colour masterbatch restricted to 2.0–3.0 wt%; trials above 3.0 wt% tint loading record longer hot-runner colour-change purge times and higher gate blush on polished surfaces. Because talc can adsorb surface moisture after silo storage, pellets showing splay on first-shot trials are dried at 80°C for 2–4 h in desiccant hoppers. Appliance compliance is evaluated under IEC 60335-1, and accessible plastic surfaces are subjected to glow-wire testing to IEC 60695-2-11; natural and white mouldings are normally classified UL 94 HB, while components that face uninsulated live parts require additional halogen-free flame retardant masterbatch at 4.0–6.0 wt% and must be re-qualified because talc can interfere with intumescent FR systems. Injection machines for these articles use clamp forces from 6,000 kN to 18,000 kN, shot capacities above 2,500 cm³, and melt temperatures of 215–235°C with mould temperatures of 25–50°C. The talc-filled melt fills wall sections between 2.0 mm and 3.5 mm; hesitation marks appear at rib intersections when filling speed is too low or when the melt temperature falls below 210°C. Venting depth is maintained at or below 0.02 mm because the talc-rich surface replicates tool texture poorly with deeper vent channels, while blocked vents generate gas burns at knitting lines. Vent cleaning is scheduled at 8 h intervals on high-volume lines, and regrind use is kept to 10 wt% in non-class-A surfaces. Terminal products include washing machine outer tub covers, detergent dispenser housings, tumble dryer base frames, and dishwasher control panel carriers.
When thin-wall electrical enclosures are moulded without vacuum venting, Seculene PPR 1240 TV30 S0 is processed at 100 phr with antistatic masterbatch at 0.5–1.0 wt% only where dust attraction must be reduced on white or light-coloured parts. Compliance for fixed electrical installations references IEC 60670-1 for boxes and enclosures, IEC 62208 for empty low-voltage switchgear enclosures, and glow-wire evaluation to IEC 60695-2-11; flammability classification is UL 94 HB in natural grades, with any UL 94 V-2 claim requiring re-qualification because talc can alter dripping behaviour during vertical burn. RoHS 2011/65/EU and REACH SVHC documentation are also requested for global shipment. The article wall stock is normally 1.2–2.0 mm, and mould temperature is held at 35–50°C to improve surface hardness and reduce tiger-stripe marking created by talc platelet reorientation during high-shear filling. In tools without vacuum venting, parting-line vents are machined to 0.01–0.03 mm depth over 4–6 mm width, and core pins are vented with self-cleaning slots; production lines that omit these details record short shots in the final 8–12% of cavity length and diesel-effect burns at knit lines. Melt temperature is controlled at 210–230°C, screw rotation and backpressure are set to keep residence time below 5 min, and hot-runner drops are profiled to 230–235°C to prevent cold slug formation at the gate. Terminal parts include junction boxes, flush-mount back boxes, terminal rail housings, and indoor meter enclosure components; outdoor exposure requires a UV-stabilized masterbatch at 2.0–3.0 wt% and weathering validation to ISO 4892-2:2013.
Downstream from contract furniture injection moulding, Seculene PPR 1240 TV30 S0 is formulated at 100 phr with colour masterbatch at 2.0–4.0 wt% and, for outdoor terrace components, a combined UV/HALS masterbatch at 2.0–3.0 wt%; reprocessed sprues and runners are incorporated at 10–15 wt% in non-load-bearing ribs, while seating shells retain virgin resin at ≥90 wt% to preserve notched Charpy impact under ISO 179-1:2023. Seating components are validated to EN 15373 for non-domestic seating, and office chair shells are evaluated under BIFMA X5.1 structural cycles; outdoor furniture parts require weathering documentation to ISO 4892-2:2013 after 500 h of accelerated exposure. The material is injection-moulded on clamp units from 4,000 kN to 12,000 kN, with melt temperature of 210–230°C and mould temperature of 20–35°C; thick boss and rib intersections are cored to maintain an effective wall thickness below 4.0 mm because the talc-filled compound forms internal voids when cooling time is insufficient. Tooling experience indicates that sink marks opposite sprue gates are controlled with holding pressure of 35–50 MPa for 6–10 s and gate diameters of 1.2–1.8 mm to delay gate freeze without extending total cycle time. Terminal products include monobloc stacking chairs, training-room chair shells, table bases, institutional storage drawers, and outdoor dining chair shells with UV-stabilized colourants.
Seculene PPR 1240 TV30 S0 is used as the 100 phr base compound for low-gloss power tool and garden equipment housings; black outdoor parts are compounded with carbon black masterbatch at 2.0–2.5 wt%, while non-black parts use weatherable pigment packages with HALS at 0.3–0.5 wt% plus an additional UV masterbatch at 2.0 wt%. Compliance for hand-held motor-operated tools follows IEC 62841-1, with plastic housing flammability assessed to UL 94 HB and glow-wire testing to IEC 60695-2-11 where user-accessible surfaces are adjacent to terminals or motor brushes. Injection moulding is run at melt temperatures of 210–235°C and mould temperatures of 30–50°C, typically with textured cavity surfaces to mask talc flow lines; multi-cavity production data show that gate blush appears on 2.5 mm nominal wall stock when injection velocity is increased beyond the point where melt front shear rate exceeds the recommended envelope. Screw rotation and backpressure are set to keep residence time below 5 min at temperatures above 220°C; thermal ageing at 110°C tends to embrittle the surface after 1,000 h, so continuous-use tools with motor compartment temperatures above 90°C require heat-stabilized antioxidant masterbatch at 0.2–0.5 wt%. For soft-grip tools, TPE overmoulding is applied in a second injection station only after the talc-filled PP substrate has cooled below 80°C, preventing interlayer delamination. Terminal articles include corded drill motor housings, lawn trimmer motor shrouds, blower housings, and garden tool handles.
Because talc-filled polypropylene random copolymer offers higher top-load stiffness than unfilled PP-R without the brittleness of heavily filled compounds, Seculene PPR 1240 TV30 S0 is converted into returnable logistics containers and light-duty pallet modules at 100 phr with antistatic masterbatch at 0.5–1.5 wt% for electronics-handling trays and UV masterbatch at 2.0–3.0 wt% where crates are stored outdoors. Pallet testing is conducted to ISO 8611-1 for rated load, deflection, and durability, while food-contact crates require migration evaluation under EU Regulation (EU) No 10/2011 and, in North America, FDA 21 CFR 177.1520 for olefin polymers. Processing uses large injection machines with clamp force from 8,000 kN to 25,000 kN, melt temperatures of 210–240°C, and mould temperatures of 20–40°C; flow across a 1,200 mm pallet deck is managed by multiple hot-runner drops and sequential valve gating to prevent premature freeze at the advancing flow front. Moulders record anisotropic shrinkage of 0.8–1.2% parallel to flow and 0.5–0.8% transverse to flow, values that require tool compensation and post-mould conditioning for 48 h at 23°C and 50% relative humidity before dimensional inspection. Finished products include stack-and-nest crates, pallet sleeves, tray modules for electronic components, and reusable distribution boxes where dimensional stability under top-load is specified.

Seculene PPR 1240 TV30 S0 PP Copolymer is specified by the manufacturer as a mineral-filled polypropylene random copolymer compound in which a talc content of 30 wt% is dispersed within a copolymer matrix. The grade carries a nominal melt mass-flow rate of 12 g/10 min when determined at 230 °C under 2.16 kg in accordance with ISO 1133-1:2022, and the filled density is normally reported near 1.13 g/cm³ according to ISO 1183-1:2019. The product designation is used for injection-moulded components requiring a balance of stiffness, dimensional stability, and shorter moulding cycles relative to unfilled PP random copolymer; it is not classified as a pipe-pressure resin, despite the PPR prefix, because the talc loading reduces long-term creep-rupture reserves. The material is supplied in pellet form and is intended for conversion on reciprocating-screw injection moulding machines rather than blown film or extrusion blow moulding lines, because the high filler content alters melt strength and parison sag behaviour in ways that are unsuitable for continuous hollow-section processes.
The numeric field 1240 is interpreted in supplier literature as a nominal melt flow rate of 12 g/10 min at 230 °C and 2.16 kg load, placing the material in a medium-flow injection-moulding range. The TV30 field denotes a talc-filled compound with approximately 30% mineral content by mass, while the matrix is a PP copolymer rather than a homopolymer. The S0 suffix is supplier-specific and is not defined by ISO 1043-1; it is generally read as a standard oxidative stabilisation package without additional antistatic or slip modifiers. Because the suffix has no universal industry meaning, any regulatory or end-use claim tied to S0 must be verified against the manufacturer’s current technical data sheet and lot certificate.
After conditioning at 23 °C and 50% RH for 40 h, representative injection-moulded specimens of Seculene PPR 1240 TV30 S0 exhibit a tensile yield stress near 26 MPa when tested according to ISO 527-2/1A/50, with yield elongation usually below 4%. Flexural modulus determined by ISO 178 is typically reported near 3,200 MPa, and notched Charpy impact strength at 23 °C under ISO 179-1/1eA falls in the range of 4.0–5.5 kJ/m². Heat deflection temperature under 0.45 MPa loading according to ISO 75-2/B is commonly cited near 115 °C, while Vicat softening temperature by ISO 306/B50 is approximately 100 °C. These values are typical data-sheet points rather than guaranteed minimums; they are influenced by mould temperature, gate geometry, and specimen orientation.
The following matrix compares the filled grade with an unfilled PP random copolymer of similar melt flow rate and with a 20 wt% talc-filled PP reference. The listed values are typical moulded-specimen data and should not be used as design allowables without confirmation on the final part geometry.
| Property | Test method | Seculene PPR 1240 TV30 S0 | Unfilled PP random copolymer | 20 wt% talc-filled PP |
|---|---|---|---|---|
| Density | ISO 1183-1:2019 | 1.13 g/cm³ | 0.90–0.91 g/cm³ | 1.05 g/cm³ |
| Melt mass-flow rate | ISO 1133-1:2022 | 12 g/10 min | 12 g/10 min | 12 g/10 min |
| Flexural modulus | ISO 178 | 3,200 MPa | 1,200 MPa | 2,300 MPa |
| Notched Charpy, 23 °C | ISO 179-1/1eA | 4.5 kJ/m² | 30 kJ/m² | 6.0 kJ/m² |
| Heat deflection temperature, 0.45 MPa | ISO 75-2/B | 115 °C | 85 °C | 100 °C |
| Mould shrinkage | ISO 294-4 | 0.8–1.2% | 1.2–1.8% | 0.9–1.3% |
In injection moulding on a 40 mm, 25:1 L/D single-screw reciprocating unit, the recommended barrel profile is 190–210 °C in the feed zone, 210–230 °C in the compression zone, and 220–240 °C at the metering zone and nozzle. A mould temperature of 30–60 °C is used to balance surface replication against post-mould shrinkage. Pre-drying at 80 °C for 2–4 h is advised when storage relative humidity exceeds 60%, because bound moisture on the talc surface can generate silver streaks at the gate and reduce weld-line strength. Back pressure of 0.3–1.0 MPa hydraulic and medium injection speed limit filler-orientation gradients that otherwise produce warpage in flat parts exceeding 2 mm wall thickness. Residence time at 240 °C should be kept below 10 min, because prolonged exposure accelerates oxidative degradation and can shift the notched Charpy value below the published range.
Weld-line tensile strength in this talc-filled material is significantly lower than bulk tensile strength. In ISO 527-2/1A specimens cut across a weld line, failure typically occurs at 45–60% of the bulk tensile yield stress, depending on melt-front temperature and holding pressure. Mould shrinkage measured on 60 mm × 60 mm × 2 mm plaques according to ISO 294-4 is anisotropic; flow-direction shrinkage and transverse-direction shrinkage can differ by 10–20% because of talc platelet orientation. For large flat electrical enclosure covers, this anisotropy requires balanced gate placement or a radial flow front to hold warpage within a 0.5 mm flatness tolerance after 24 h at 23 °C.
The PPR prefix may suggest pipe-grade resin, but Seculene PPR 1240 TV30 S0 is directed toward rigid non-pressure assemblies in which dimensional stability and flexural modulus are more important than long-term hydrostatic strength. When unfilled PPR is replaced by this 30 wt% talc-filled copolymer, flexural modulus increases from approximately 1,200 MPa to 3,200 MPa, and mould shrinkage decreases from approximately 1.6% to 1.1% under comparable cavity conditions. The trade-off is a reduction in notched Charpy impact strength from roughly 30 kJ/m² to 4.5 kJ/m² at 23 °C, and the material should not be used for pressure pipes, fittings, or vessel components without long-term hydrostatic testing according to ISO 9080. Published creep-rupture data for this exact grade are limited; any load-bearing replacement of a PPR pipe resin therefore requires tensile creep and fatigue validation on the finished moulding.
Continuous exposure to aromatic hydrocarbons, chlorinated solvents, or strong oxidising acids at temperatures above 23 °C produces surface swelling and loss of tensile strength in this polypropylene copolymer matrix. Compatibility testing according to ISO 175 is required before use with automotive fluids, cleaning agents, or sealing compounds. The material is not inherently flame retardant; standard UL 94 evaluation frequently gives an HB classification at thicknesses above 3 mm, but the final classification must be determined on the actual wall section. Long-term air ageing above 130 °C is outside the recommended service envelope for an unmodified PP random copolymer; heat-ageing tests such as ISO 188 should be performed before components are exposed to sustained elevated temperature. In applications requiring food-contact compliance, the converter must separately verify the final article under EU Regulation 10/2011 or FDA 21 CFR, because the talc filler and stabiliser package are not automatically covered by a base-polymer listing.
The S0 suffix is supplier-specific and does not by itself certify food-contact, medical, or potable-water suitability. Within the manufacturer’s grade structure, S0 is used to indicate the standard antioxidant package for injection moulding, without additional antistatic or slip additives. Warehousing should be conducted below 50 °C and below 60% RH, and the supplier’s shelf-life statement is typically 12 months from the date of certification when bags are unopened. Exposure to direct sunlight or ultraviolet radiation for storage periods beyond the certified interval can shift the notched Charpy impact strength and increase surface chalking; outdoor weathering must be qualified by ISO 4892-2 or a comparable accelerated weathering method, because talc-filled PP grades are not generally supplied with long-term UV stabilisation under this suffix.
Flat electrical enclosure covers, HVAC fan shrouds, automotive interior carriers, and appliance structural brackets are process-sensitive application areas for Seculene PPR 1240 TV30 S0. In a two-cavity enclosure cover tool with a 1,800 kN clamp force and a single hot tip, measured after-mould shrinkage was 0.9% in the flow direction and 1.2% in the transverse direction after 24 h at 23 °C; this anisotropy is controlled by relocating the gate to create a more radial flow front and by raising mould temperature to 60 °C. Such parts are additionally checked for warpage using a flatness fixture with 0.5 mm tolerance before release, and the same dimensional controls apply to HVAC shrouds where sealing surfaces must remain flat after assembly.
