Known as "the white o-ring", Chemrez is a white, perfluoroelastomer compound with high temperature and chemical resistance

Compared with other elastomers, Chemraz is normally more resistant to swelling and embrittlement, and will retain these properties for a longer period of time. Compared with metal seals, Chemraz is easily installed and conforms to the sealing surface despite irregularities that may occur due to improper assembly or wear. Compared with PTFE seals, Chemraz is not likely to creep or cold flow.

CHEMRAZ o-rings retain their elastic properties longer in harsh chemical environments at temperatures from -30°C to 220°C. Recommended for use in a variety of hot, corrosive environments.

It has all the properties and inertness of PTFE. Great for Pharmaceutical or food applications where high purity is a must.
