Product Overview
Polymer Processing Aid (PPA) That Eliminates Melt Fracture & Unlocks Throughput
Polymer Processing Aid (PPA) is a class of fluoropolymer-based additives that, at extremely low loading levels (50 – 800 ppm), form a dynamic lubricating layer along the die wall during polyolefin extrusion. This invisible interface eliminates melt fracture, reduces die build-up, lowers head pressure, and dramatically increases continuous run time — all without altering the resin’s mechanical, sealing, printing, or bonding properties.
Sychem’s PPA series spans 13 application-specific grades covering blown film, cast film, pipe, blow-moulding, wire & cable, raffia, sheet & profile, masterbatch, and large petrochemical polyolefin reactors. Selected grades extend coverage into PP, PVC, PS, PA, PET, PC, PMMA and ABS, giving compounders a single, predictable additive platform across both commodity and engineering thermoplastics.
All grades supplied by Sychem are sourced from a qualified Chinese fluoropolymer manufacturer whose PPA technology has been validated by SABIC, BASF, Clariant, Lubrizol, Sinopec, PetroChina, Samsung, LG, and other leading polymer producers.

Performance Benefits
Six processing gains at ppm-level loading
PPA delivers measurable improvements across the entire extrusion line — surface quality, output rate, energy consumption, and downtime — without changing the resin’s downstream performance.
01 / SURFACE QUALITY
Eliminate Melt Fracture
A dynamic lubricating layer at the die wall removes sharkskin, orange-peel, and stick-slip defects — producing glossy, smooth film and profile surfaces.
02 / UPTIME
Reduce Die Build-up
Drastically lowers die deposit accumulation, extending continuous run time and cutting line stoppages for cleaning — direct savings on labour and lost production.
03 / THROUGHPUT
Higher Output, Less Energy
Reduces extruder torque and melt pressure — at equal back-pressure, line speed can be increased by 10 – 30%, while energy consumption per kg drops accordingly.
04 / PIGMENT DISPERSION
Improved Colour & Carbon Black Loading
Improves pigment-resin compatibility — raises maximum carbon black loading in black masterbatch and boosts the gloss and chromatic strength of colour concentrates.
05 / VERSATILITY
Broad Resin Compatibility
Works in mLLDPE, LLDPE, HDPE, LDPE, EVA and PP. Selected grades extend into PVC, PS, PA, PET, PC, PMMA and ABS — covering both commodity and engineering polymers.
06 / COMPLIANCE
FDA 21 CFR 177.1520
Mainstream grades meet US FDA 21 CFR 177.1520 — qualified for food-contact polyolefin films, beverage packaging, medical disposables, and high-end consumer goods.
Industries Served
Applications across the polyolefin extrusion universe
PPA is essential wherever polyolefins are extruded under high shear — from agricultural film and pipe lines to wire & cable plants and resin-producer reactors.
Blown & Cast Film
Eliminates sharkskin on mLLDPE and LLDPE, enables higher BUR ratios, and increases line speed on multi-layer co-extrusion. Critical for thin-gauge stretch, packaging, and lamination films.
Agricultural Film
Greenhouse, mulch, silage, and multi-layer ag film. PPA improves clarity and reduces gauge variation, extending film life and crop yield in high-volume seasonal production.
Pipe & Profile
HDPE pressure pipe, PE-RT under-floor heating, PP-R hot/cold water pipe, and corrugated drainage pipe. PPA enables smoother inner walls and higher haul-off rates.
Wire & Cable
Silane-crosslinked PE insulation, LDPE jacketing, halogen-free flame-retardant compounds, and high-voltage cable insulation. Improves surface gloss and reduces line stoppages.
Masterbatch & Compounding
Carrier-resin masterbatch, high-loading black/white concentrates, additive masterbatch. PPA improves pigment wetting and enables higher pigment loadings without dispersion defects.
Petrochemical Resin Producers
Reactor-grade PPA dosed directly at the polymer plant — improves bin flow, prevents reactor fouling, and gives downstream converters consistent, ready-to-process resin.
Selection Guide
Resin compatibility & dosage by application
PPA reaches optimum performance at very low loading levels. The dosage required depends on resin family, processing temperature, and shear conditions.
Typical Loading Range
Loading levels above are general guidelines. The recommended starting practice is to compound a 2 – 3% PPA masterbatch via twin-screw extruder, then let-down to the target final loading. Conditioning time on first use is typically 20 – 60 minutes.
Comparison
PPA vs conventional processing aids
Why fluoropolymer PPA outperforms traditional fatty-acid lubricants and silicone-based slip agents in modern polyolefin extrusion.
Processing Guide
How to use PPA on your line
Dispersion of PPA in the resin is the single most important factor for performance. The recommended workflow below gives consistent, fully active results across all polyolefin extrusion lines.
STEP 01
Compound a 2 – 3% PPA Masterbatch
Pre-disperse PPA into a carrier resin via twin-screw extruder at 2 – 3% loading. Pre-dispersion is what guarantees PPA’s full effectiveness in downstream let-down.
STEP 02
Let-Down to Target Loading
Blend the PPA masterbatch into the production resin to reach the final target ppm. Loading depends on resin type, equipment, and shear conditions — see the dosage table above.
STEP 03
Allow 20 – 60 min Conditioning
On first use, the lubricating layer takes 20 – 60 minutes to fully form on the die. Lines running PPA continuously experience no conditioning lag on grade changes.
