Universal Perfluorolelastomer (FFKM)

Greene Tweed’s Chemraz® 541 is a universal, high-strength black FFKM compound designed for demanding applications. It boasts excellent chemical and compression set resistance and operates at temperatures up to 446°F/230°C.

Thanks to its broad chemical compatibility, temperature range, and shape versatility, Chemraz® 541 is an ideal choice for demanding environments and processes requiring excellent chemical resistance. Chemraz® 541 maintains its properties when exposed to a broad array of fluids including acids, amines, aromatics, and hot water, steam.

We leverage compounding experience, manufacturing expertise, and engineering knowledge to ensure customers receive the optimal material and design for their application.

Features & Benefits
