With the resilience and sealing force of an elastomer and chemical resistance approaching that of PTFE, Chemraz® offers superior performance for engineered components such as O-rings, gaskets and seals. Aggressive fluid handling applications require versatile and long-lasting elastomers, and Chemraz fits the bill. Chemraz is resistant to a broader range of chemicals than silicone, EPDM, Viton and other standard elastomers, including inorganic and organic acids, bases, ketones, esters, aldehydes, alcohols and fuels. Chemraz seals and gaskets resist leakage caused by compression set even at temperatures up to 615°F (324°C). Chemraz seals and gaskets have exceptional resistance to steam above 350°F (177°C). Repeated sterilization is also not a problem--Chemraz seals and gaskets withstand all conventional sterilization methods without degradation.
