Processing SABIC PP 5705P on a single-screw sheet line with a barrier screw of L/D 30:1 to 33:1 and a grooved feed bushing requires a flat reverse temperature profile to prevent bridging of the low-MFR homopolymer in the feed throat. The extruder zones are set from 190°C in the feed zone to 230°C in the metering zone, with die temperature held between 235°C and 245°C. Melt temperature at the die exit is maintained between 230°C and 250°C, because below 230°C the melt strength increases enough to reduce output stability on wider sheet lines, while above 250°C thermo-oxidative degradation increases yellowing risk. Sheet thickness for dairy cups and portion packs is produced at 0.35 mm to 1.2 mm, with the die gap set approximately 10% wider than the target sheet thickness to compensate for draw-down. In-house regrind from skeletal scrap is added at 10 wt% to 20 wt%; higher addition shifts the melt flow rate under ISO 1133-1:2022 and increases die lines on polished rolls. White or colored masterbatch is metered at 1 wt% to 3 wt% using gravimetric dosing. Plug-assisted thermoforming of cups, portion-packs, and tamper-evident lids uses aluminum plugs preheated to 120°C to 140°C, mold surface temperature of 30°C to 60°C, and part draw ratios between 1.5:1 and 3:1. The Vicat softening point under ISO 306-A50 is near 152°C, so sheet surface temperature before forming must exceed that threshold for uniform wall distribution. Compliance for direct food contact is evaluated under FDA 21 CFR 177.1520 and EU 10/2011, with the latter requiring migration verification under Annex I fatty-food simulants if wall thickness falls below 0.2 mm. Published data for high-temperature hot-fill use above 90°C is limited, so converter trials with the specific lid geometry and fill temperature are required before production.
In PP twin-wall sheet production, SABIC PP 5705P is run at a slightly higher rear barrel temperature than in thin-gauge sheet because the corrugated profile creates higher backpressure and requires less shear heating in the compression zone. The melt temperature at the die entry is set at 220°C to 240°C. A flat 90 mm extruder with L/D 30:1 typically operates with the zone settings shown in the following table.
| Extruder zone | Set temperature | Function |
|---|---|---|
| Feed | 190–200°C | Preheating and solids conveying |
| Compression | 210–230°C | Melting and homogenization |
| Metering | 230–240°C | Pressure generation |
| Adapter | 230–235°C | Melt transfer |
| Die | 235–245°C | Sheet formation |
After the die, the web enters a calibrator/corrugator unit where vacuum holes shape the flute perpendicularly. Flute height is controlled between 2 mm and 5 mm, and board basis weight is adjusted from 500 g/m² to 1200 g/m². Chill-roll water temperature is held at 15°C to 25°C, and line speed is limited by web sag between the die and the polishing stack; output stability is typically lower than for solid sheet of equivalent thickness. Regrind content for industrial packaging can reach 30 wt% if the flake is low-odor and free of paper labels, but for food-contact interlayer sheets regrind is restricted to clean in-house material at 10 wt% maximum. End products include returnable transit boxes, signage blanks, floor protection boards, and interlayer pads. Dimensional stability after die cutting is controlled by annealing at 80°C to 90°C for 30 min before final stacking. The grade is not formulated as a flame-retardant material, so separate FR masterbatch qualification under EN 13501-1 or relevant regional building standards is required where construction-sector fire classification is mandatory.
In coextruded barrier sheet for shelf-stable convenience-food trays, SABIC PP 5705P is processed as the outer PP layers in a five-layer A/B/C/B/A configuration. The PP cap layers account for 35 wt% to 45 wt% of the total structure on each side, while the central EVOH barrier is 6 wt% to 10 wt% and the tie resin is 3 wt% to 5 wt% per adhesive layer. Direct adhesion of homopolymer to EVOH is insufficient, so maleic anhydride-grafted tie resin is applied. The extruder for the PP cap layers is set to produce melt temperature 235°C to 250°C; the EVOH and tie layers are kept within their own supplier-specified thermal limits. The feedblock and die are maintained at 240°C to 245°C. Sheet thickness for thermoformed trays is 0.6 mm to 1.5 mm. Post-extrusion forming uses cavity temperature 20°C to 40°C and sheet surface temperature 150°C to 165°C. Compliance is assessed under EU 10/2011 and FDA 21 CFR 177.1520, with the EVOH layer under 21 CFR 177.1360 and tie resins under their own food-contact notifications. Terminal products include shelf-stable retort trays, microwaveable bowls, and modified-atmosphere protein trays. The operational boundary for 5705P in this structure is not the PP layer but the EVOH thermal history; the line must not hold at 240°C for more than 6 min without scrap purging because degraded EVOH gel particles create visible film defects and reduce interlayer peel strength.
High-clarity PP sheet for cosmetic trays, confectionery inserts, and stationery covers is produced from SABIC PP 5705P on a high-polish vertical three-roll stack. If the first chill-roll temperature is set below 15°C, the outer skins freeze too rapidly, producing low haze but also increasing differential shrinkage across the sheet width and raising the risk of transcrystalline skin layers that delaminate under repeated flexing. The practical window for roll temperatures is 18°C to 25°C for the upper roll, 25°C to 30°C for the middle roll, and 30°C to 40°C for the bottom roll. Melt temperature at the die exit is held between 240°C and 260°C to minimize melt memory and improve roll replication; the die gap is set at 0.8 mm to 1.2 mm for final sheet from 0.3 mm to 0.7 mm. Anti-static masterbatch is dosed at 0.5 wt% to 1.5 wt% where the sheet is used for printing and high-speed die cutting. Slip additives are not intrinsic to the grade and are added only after printability trials because migration can reduce surface tension and ink adhesion. The material does not require pre-drying at storage RH below 60%; at higher RH, predrying at 80°C for 2 h prevents surface splay. Compliance for cosmetic and stationery end uses is commonly limited to general product safety under REACH and heavy-metal content under RoHS 2011/65/EU. Terminal products include clear lids for high-end confectionery, transparent file folders, display trays, and folded boxes. Processors should verify that recycled PP stream content does not exceed 20 wt% in these thin-gauge high-clarity applications, because higher recycled content increases gel counts and visible haze variation.
For oriented tape and monofilament conversion, the process window is narrower than for sheet extrusion because the homopolymer is stretched in the semi-solid state and any crystallinity gradient formed during water-bath cooling is magnified. A single-screw extruder with L/D 25:1 to 30:1 feeds a slit die or a spinneret; melt temperature is held at 230°C to 250°C. The extrudate passes through a water bath at 30°C to 50°C, then to a hot-air oven or hot-plate drawing unit at 110°C to 130°C. Draw ratio is set at 5:1 to 8:1 for strapping and carpet-backing tapes; ratios above 8:1 produce fibrillation in homopolymer without a nucleating package. Relaxation after the drawing oven is 3% to 5% to reduce shrinkage. Where UV stabilization is required, a 0.5 wt% to 1.0 wt% hindered amine light stabilizer masterbatch is added; where flame-retardant grades are specified, the converter should verify whether the FR system is compatible with high draw ratios. Published data for this specific configuration is limited, so line trials are required to verify tenacity per ISO 2062 and hot-air shrinkage per ASTM D4974. End products include PP strapping tape, woven sack tape, industrial twine, and carpet backing. Compliance for these industrial products is limited to REACH and occupational exposure limits for volatiles; food-contact certification is not required.
Deep-draw thermoforming from heavy-gauge SABIC PP 5705P sheet is controlled primarily by sheet temperature uniformity and plug material selection. Sheet thickness between 2 mm and 5 mm is extruded at melt temperature 230°C to 250°C and preheated to 160°C to 170°C on both sides before forming. Draw ratios from 2:1 to 4:1 are achieved with syntactic foam or hardwood plugs coated with low-friction fabric; plug surface temperature is held at 90°C to 110°C to avoid chilling the sheet prematurely. Mold temperature is set between 40°C and 70°C to reduce internal stress and corner shrinkage. Industrial trays and returnable dunnage produced from this grade are not impact-modified, so corner cracking under repeated drop load requires rounding radii above 4 mm or switching to an impact-copolymer skin layer in coextruded formats. Pigment masterbatch is added at 2 wt% to 4 wt% for color-coded logistics trays, and carbon black masterbatch at 3 wt% to 5 wt% is used where ESD-protective packaging is specified. Dimensional change after exposure to repeated wash cycles is evaluated by thermal linear expansion coefficient under ISO 11359-2, typically between 0.9 × 10⁻⁴ K⁻¹ and 1.2 × 10⁻⁴ K⁻¹ for PP homopolymer. Compliance for industrial non-food dunnage is governed by general REACH registration and RoHS 2011/65/EU heavy-metal limits; products destined for automotive spare-part return loops may require additional volatile organic compound testing under applicable OEM standards. Terminal products include logistics trays, dunnage bins, compartment dividers, and returnable industrial packaging.

SABIC PP 5705P is a polypropylene random copolymer supplied by SABIC for injection molding applications in which optical clarity, moderate impact resistance, and high flow length are required. The grade carries a melt flow rate of 25 g/10 min at 230°C under 2.16 kg load when tested to ISO 1133-1 and a density of 905 kg/m³ when tested to ISO 1183-1. Random ethylene comonomer insertion shortens the average isotactic sequence length and suppresses spherulitic growth; the resulting morphology reduces haze and increases ductility compared with homopolymer polypropylene. The same microstructure lowers flexural modulus and heat deflection temperature relative to stiff homopolymer grades. PP 5705P therefore occupies the high-flow random copolymer segment for thin-wall packaging, transparent housewares, medical disposables, and caps or closures.
Melt processing of PP 5705P is normally conducted on three-zone reciprocating-screw injection molding machines with a shut-off nozzle and positive sprue break. A melt temperature range of 230°C to 250°C is used. Below 230°C, the high-molecular-weight tail may produce fill defects in ribs thinner than 0.6 mm; above 250°C, thermo-oxidative chain scission accelerates and molecular weight distribution narrows. The loss of melt strength can produce jetting, gate blush, and brown streaks if residence time exceeds the degradation threshold. A barrel temperature profile with rear zone 180°C to 200°C, center zone 210°C to 230°C, front zone 230°C to 250°C, and nozzle 230°C to 250°C is typical for thin-wall molding. Published data for this specific configuration is limited; mold-filling simulation with corrected Cross-WLF viscosity coefficients should be performed when wall thickness falls below 0.8 mm.
Mold temperature is maintained between 10°C and 40°C. Lower mold temperatures shorten cooling time but increase frozen-in orientation and reduce impact; higher mold temperatures improve surface gloss and dimensional stability at the cost of longer crystallization time. Random copolymer has a longer quiescent crystallization half-time than homopolymer; cooling time should therefore be verified by pressure decay, infrared surface pyrometry, or ultrasonic ejection sensors rather than by homopolymer cycle standards. Because the melt flow rate is 25 g/10 min, PP 5705P is sensitive to flash when clamp force is marginal. The required clamping force should be calculated from cavity pressure and projected area; in thin-wall cavities with wall stock below 0.8 mm, cavity pressures up to 80 MPa may be required.
Flow length-to-wall thickness ratios for PP 5705P in thin-wall molds often fall between 150:1 and 200:1. These ratios are achievable only when injection speed and melt temperature are optimized. Low melt temperature produces short shots, elevated birefringence, and warpage; high melt temperature reduces melt strength and increases gate stringing. Injection speed should be set to fill the cavity within 0.5 s to 1.5 s for wall stock between 0.5 mm and 1.0 mm. Slower fill freezes the flow front and can create diesel-effect marks. Hold pressure is typically 60% to 80% of injection pressure and should be maintained until gate freeze. For cold-runner systems, runner diameter should not fall below 3.0 mm to avoid premature freeze-off; hot-runner manifolds should use balanced melt channels and open-pipe nozzles with diameter 1.0 mm to 1.5 mm.
The table below consolidates representative datasheet values for SABIC PP 5705P. Values are typical and should not be interpreted as specification limits.
| Property | Standard | Typical Value |
|---|---|---|
| Melt flow rate at 230°C/2.16 kg | ISO 1133-1 | 25 g/10 min |
| Density | ISO 1183-1 | 905 kg/m³ |
| Tensile stress at yield | ISO 527-2 | 30 MPa |
| Tensile strain at yield | ISO 527-2 | 11% |
| Flexural modulus | ISO 178 | 1200 MPa |
| Notched Izod impact at 23°C | ISO 180/A | 5.0 kJ/m² |
| Heat deflection temperature at 0.45 MPa | ISO 75-2/B | 85 °C |
The 25 g/10 min melt flow rate is approximately twice the value used for many extrusion-grade random copolymers; this reduces fill time and injection pressure but narrows the residence-time window. The 5.0 kJ/m² notched Izod impact at 23°C indicates moderate room-temperature toughness; at sub-zero temperatures the ductile-to-brittle transition occurs above that of heterophasic impact copolymers. Specimens for mechanical testing are injection molded according to ISO 294-1; users should not compare ISO values directly with ASTM D638 or ASTM D256 data because specimen dimensions and test speeds differ.
When wall thickness drops below 0.8 mm, optical performance is governed by frozen-in spherulite size, mold surface replication, and flow-induced crystallization. PP 5705P provides lower haze than homopolymer at equal wall thickness because random ethylene incorporation suppresses spherulitic growth. If a sorbitol-based clarifier is present in the formulation, processing above 250°C can destroy its effectiveness and produce plate-out on the mold surface. The same condition increases yellowing and should be avoided. High shear rates above 10,000 s⁻¹ in wall stock below 0.4 mm can generate viscous heating; the actual melt temperature should be measured by needle pyrometer during air shot and should not exceed 260°C.
A polished SPI-A1 mold surface is required for low haze in transparent parts; textured surfaces reduce gloss and mask flow marks but also increase haze. Haze should be specified only with the test method and plaque thickness, commonly ASTM D1003 on a 1 mm or 2 mm plaque. Birefringence and flow marks arise from shear-induced crystallization and slow quenching; increasing mold temperature to 25°C to 40°C and reducing injection speed can improve optical isotropy but may extend cycle time. For food-contact thin-wall containers, organoleptic neutrality should be confirmed after repeated recycling of post-industrial regrind. Polar contaminants and printing inks in regrind can degrade taste and odor even when the base resin meets food-contact standards. The addition of regrind above 15 wt% in transparent parts may increase yellowing and haze due to accumulated thermal history.
Because polypropylene does not undergo hydrolytic degradation, moisture-related defects usually arise from surface condensation on cold pellets rather than absorbed water. At relative humidity above 60%, pellets brought into a warm molding area can develop surface moisture that produces splay and voids, especially in hot-runner systems. A desiccant dryer operating at 80°C for 2 h is sufficient to remove surface moisture; the drying air dew point should be at or below -18°C. Longer drying does not damage the resin but increases energy consumption without improving process stability. For a machine consuming 10 kg/h of PP 5705P, a hopper dryer with air flow of at least 1.5 m³/min and inlet air temperature of 80°C is sufficient. The hopper should be insulated to prevent re-condensation.
General-purpose polypropylene screws with L/D ratio of 20:1 to 22:1 and compression ratio of 2:1 to 2.5:1 are adequate for PP 5705P. A metering section of 4D to 5D improves melt homogeneity. Back pressure is typically kept between 4 MPa and 8 MPa to avoid excessive shear heating. With a 25 mm diameter screw and L/D 20:1, screw speeds of 100 min⁻¹ to 150 min⁻¹ usually recover the shot within the cooling window; screw speeds above 200 min⁻¹ can generate melt temperatures above the set point by viscous shear. The screw should use a ring non-return valve; worn ring clearances above 0.2 mm produce shot-weight drift and inconsistent cavity filling. Regrind is permitted up to 30 wt% in non-appearance applications; for transparent parts, regrind content above 15 wt% may measurably increase haze and yellowing. Consistent regrind particle size prevents hopper bridging, and a magnet or screen pack upstream of the feed throat reduces contamination from metal or paper.
Regulatory assessment of PP 5705P begins with the base polypropylene resin, which can be evaluated against FDA 21 CFR 177.1520 for repeat-contact food packaging and EU 10/2011 for plastic materials intended for contact with food. Specific migration limits for total migration and metal additives apply under the time-temperature profile of the intended use. The end user is responsible for verifying that colorants, clarifiers, and processing stabilizers in the commercial formulation appear on the relevant positive list. PP 5705P is not a flame-retardant grade; it should not be used in electrical enclosures requiring glow-wire ignition temperature compliance per IEC 60695-2-11 without additional testing.
PP 5705P should not be exposed to strong oxidizing acids, aromatic hydrocarbons, or chlorinated solvents at elevated temperatures; these agents can cause stress cracking or extractive mass loss. Outdoor weathering resistance is limited without stabilization; where UV exposure is required, hindered amine light stabilizers and UV absorbers should be evaluated by ISO 4892-2 or ASTM G154. Autoclaving at 121°C may exceed the heat deflection temperature and cause dimensional distortion; PP 5705P should not be used for repeated steam sterilization unless the part geometry and load are validated.
Compared with a high-ethylene heterophasic impact copolymer, PP 5705P displays lower notched Izod impact at -20°C but higher transparency. Compared with homopolymer polypropylene, it shows lower flexural modulus and heat deflection temperature but better haze and room-temperature impact. In applications where top-load strength and heat deflection temperature are controlling, a stiff homopolymer should be selected; in applications requiring low-temperature ductility, a heterophasic impact copolymer is preferable. Within the SABIC PP range, film-grade random copolymers are formulated at lower melt flow for bubble stability and draw control, while PP 5705P is formulated for shear-thinning behavior in thin-wall injection molding. Direct substitution of PP 5705P for a homopolymer such as SABIC PP 500P in a clear container is not mechanically neutral because the homopolymer increases flexural modulus but raises haze and lowers notched Izod impact.
