Facing Die Build-Up, Rough Surfaces, and Low Output? Here's the PFAS-Free Way to Solve It

HDPE and MDPE pipes form the backbone of modern water infrastructure - delivering safe, durable, and high-pressure performance.

Yet during extrusion, manufacturers often face recurring issues: die build-up, melt fracture, unstable back pressure, and inconsistent surface finish. These problems not only affect pipe appearance but also reduce line speed, increase maintenance downtime, and raise energy costs.

For decades, fluoropolymer-based processing aids such as 3M Trademark Dynamar Trademark PPA have been used to ease these challenges. However, with growing PFAS restrictions worldwide, the pipe industry urgently needs a non-fluorinated, sustainable alternative - one that maintains or exceeds existing performance standards.

Why the Pipes Industry Is Moving Beyond PFAS-Based PPAs

PFAS (Per- and Polyfluoroalkyl Substances) are under growing scrutiny due to their persistence in the environment and potential health risks.According to the EU REACH Regulation and US EPA 2024 Roadmap, PFAS-containing processing aids will face progressive bans or strict reporting requirements.For manufacturers exporting pipes to Europe or North America, compliance is no longer optional - it's a market necessity.

As a result, pipe producers are actively seeking PFAS-free polymer processing aids that can deliver the same extrusion smoothness and stability, without environmental or reputational risk.

Introducing the SILIKE SILIMER Series - A 100% Pure, PFAS-Free, Silicone-Based PPA

Developed by Chengdu SILIKE Technology, the SILIMER Series represents a major breakthrough in extrusion processing aids.

Unlike fluoropolymer PPAs, SILIMER silicon based plastics additives are based on a pure modified copolysiloxane molecular structure, combining the low surface energy of silicone with polar modified groups that actively migrate to metal surfaces.

Once at the die wall, these molecules form a stable lubricating layer, reducing melt friction, stabilizing shear stress, and minimizing die pressure - all without using any fluorine components.

SILIMER PFAS-Free PPAs are typically compounded into a masterbatch and added at low dosage levels (500-1000 ppm) to HDPE, MDPE, LLDPE, LDPE, PP, or PERT systems.

Even in small amounts, they provide major processing improvements:

Smoother polymer flow & melt uniformity

Reduced back pressure and torque

Elimination of shark-skin and die drool

Longer cleaning cycles and stable line speed

Higher output and lower energy consumption
