Chemraz® 541

Greene Tweed’s Chemraz® 541 is a universal, high-strength black 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. Chemraz® 541 maintains its properties when exposed to acids, acrylates, alcohols, aldehydes, amines, aromatics, esters, ethers, halogens, ketones, hot water, and steam.

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

Greene Tweed's scientists and engineers are careful and methodical in the development of new compounds, undertaking numerous studies of processing variability to ensure our manufacturing team can deliver a consistent, quality product.

Excellent chemical resistance and maximum temperature operation to 446°F/230°C
Low-temperature capabilities 3°F/-16°C
High strength and good compression set resistance for tough industrial applications
Improved chemical resistance, especially in acids, amines, and steam
Improved tensile strength and modulus should allow for better performance in dynamic applications and those requiring higher loads
For Semiconductor applications, reduced outgassing for 14 nm and smaller, which helps to reduce the risk of pump down time and minimize process impact
High elongation values ensure easy installation of o-rings
Custom geometry availability upon request
Global manufacturing capabilities
Available as o-rings and slabs; other geometries upon request
