Why the Need for PTFE (PFAS) Alternatives?

In today’s rapidly evolving world of sustainable materials, industries are facing increasing pressure to adopt environmentally friendly solutions. Engineering plastics, known for their durability and versatility, are no exception. For years, PTFE (Polytetrafluoroethylene) has been go-to materials for engineering plastics, prized for their chemical resistance, low friction, and high thermal stability.

However, PTFE belongs to the PFAS (Per- and Polyfluoroalkyl Substances) family, which has raised important environmental concerns due to its persistence and resistance to degradation. Often called “forever chemicals,” PFAS have the potential to accumulate in ecosystems and pose risks to human health, including issues related to the immune and endocrine systems, liver function, and even more serious conditions like cancer.

In response to these challenges, many countries are tightening regulations around PFAS substances. For instance:

The European Union’s REACH regulation has identified PFAS as a “substance of very high concern,” leading to strict restrictions on its use.

The U.S. Environmental Protection Agency (EPA) has initiated monitoring and phase-out plans for PFAS chemicals.

So, how can engineering plastics maintain their high performance while minimizing environmental impact? PFAS-Free and PTFE-Free solutions provide the ideal answer, delivering the same high-performance benefits without the environmental and health risks.

What is the alternative to PTFE? High-Performance, PFAS-Free Additives for Engineering Plastics

Introducing SILIKE Fluorine-Free Wear-Resistant Additives and PTFE Alternatives

Key Advantages of PTFE Replacement Additive SILIKE LYSI-701 for Engineering Plastics:

1. Fluorine-Free Composition: A fully PFAS-free formulation that aligns with rigorous global environmental standards.

2. Enhanced Wear Resistance: Even a small amount of this additive can significantly improve the durability and lifespan of engineering plastics when compared to PTFE.

3. Superior Lubrication: It effectively reduces friction and enhances processing efficiency, driving better performance.

4. Wide Applicability: Suitable for diverse materials such as PA6, PA66, PC, ABS, POM, PBT, PPS, and many more engineering plastics.

Laboratory tests verify: 3 wt% LYSI-701 in POM exhibits superior wear resistance and a lower coefficient of friction (COF) compared to 10 wt% PTFE under identical test conditions.
