SILIKE highlights PFAS-free processing aids at CHINAPLAS and K Show

Chengdu SILIKE Technology used CHINAPLAS and the K Show to pitch fluorine-free polymer processing aids as brands face tighter PFAS scrutiny in Europe, North America and Asia. The company says its SILIMER line is designed to help extrusion users reduce melt fracture, die build-up and scrap without changing equipment.

Why it matters: - Global plastics buyers are under growing pressure to cut PFAS in selected applications as regulations and sustainability expectations tighten. - Packaging, wire and cable, pipe, automotive and industrial polymer makers are looking for alternatives that protect compliance without hurting throughput. - The industry challenge is not just substitution. Processors need stable extrusion, acceptable scrap levels and lower maintenance costs.

What happened: - Chengdu SILIKE Technology Co., Ltd. showcased its PFAS-free polymer processing aid portfolio at recent CHINAPLAS and K Show editions. - The company drew attention from international brand owners, converters and Tier-1 suppliers looking for alternatives to fluoropolymer-based processing aids. - SILIKE framed the SILIMER series as a fluorine-free option for extrusion applications in polyolefin and selected engineering thermoplastics.

The details: - Traditional fluoropolymer-based processing aids have long been used to reduce melt fracture and surface defects in extrusion. - Buyers at the shows focused on how to remove fluorinated additives without raising scrap rates or production costs. - The regulatory backdrop includes the EU Packaging and Packaging Waste Regulation and broader chemical management policies in major markets. - Those rules do not amount to an immediate global ban on fluoropolymer-based processing aids, but they point to tighter control of persistent fluorinated substances. - In processing, removing conventional PPAs can raise melt viscosity and internal friction in high-molecular-weight resins and LLDPE. - The result can be melt fracture, die pressure swings, die build-up and higher scrap. - SILIKE says the SILIMER series is designed to improve melt flow behavior and reduce surface defects during extrusion. - The company positions the products as potential alternatives, not direct one-to-one replacements with identical performance. - SILIKE says the additives can support improved extrusion stability, reduced surface defects, lower die-cleaning frequency in some applications and PFAS reduction strategies. - SILIKE says the chemistry uses a tri-segment organo-modified polysiloxane architecture with polar, polysiloxane and non-polar compatibility segments. - The company says that structure helps disperse the additive in PE and PP, lubricate the melt and anchor to metal surfaces inside the screw, barrel and die. - SILIKE says that mechanism can reduce polymer-to-metal adhesion, lower shear resistance and help control melt fracture, die drool and pressure fluctuation. - The SILIMER 9400, 9300, 9200 and 9100 series are 100% active, fluorine-free additives intended for resin production and compounding. - SILIKE says those grades are used in functional masterbatches and then downstream in film, cable, pipe, fiber and other extrusion applications. - The carrier-based masterbatch line includes SILIMER 9406, 9301, 9201 and 5090 for direct industrial use. - SILIKE says those masterbatches are used in film, pipe, sheet, fiber, artificial grass, and wire and cable applications. - The products can be added during resin manufacturing, compounding or downstream extrusion, depending on production setup. - SILIKE says the additives are compatible with conventional extrusion and compounding systems and do not require equipment modification. - The company says it has demonstrated commercial applications in blown film, cast film, multilayer film, fiber, monofilament, cable, pipe, masterbatch manufacturing and compounding. - SILIKE says those applications cover both polyolefin and recycled polyolefin resin processing systems. - The company also says the products can help meet REACH, RoHS and EU PPWR-related requirements. - A European packaging representative at the show said the main challenge is maintaining stable production efficiency and acceptable scrap levels while transitioning away from established processing systems.

Between the lines: - The PFAS debate is pushing technical teams to evaluate not just compliance labels, but whether a substitute behaves like a true manufacturing input. - SILIKE’s pitch is aimed at that middle ground: a fluorine-free system that preserves line stability well enough for commercial scale-up. - The emphasis on masterbatch formats suggests the company is targeting easier adoption in existing extrusion lines rather than a full process overhaul.

What's next: - Global brand owners and converters are expected to keep reviewing formulations as PFAS-related rules evolve. - SILIKE is directing interested buyers to technical documentation, application case studies and custom formulation consultations at the company's announcement. - The key test will be whether processors can maintain quality, speed and cost targets as fluoropolymer-based PPAs face more scrutiny.

The bottom line: - SILIKE is betting that fluorine-free processing aids can become a practical replacement path for extrusion users facing rising PFAS pressure.
