Kalrez® Spectrum™ 0040 perfluoroelastomer parts are specifically designed for low-temperature environments where significant chemical resistance is required. Proprietary polymer and cure technology promotes low-temperature sealing performance (-42°C) of Kalrez® Spectrum™ 0040 parts to temperatures typically unattainable for perfluoroelastomers parts.
Kalrez® Spectrum™ 0040 is an excellent choice in applications such as couplings for the chemical transportation industry, or for other applications where chemical resistance and elasticity are required in some of the coldest environments.
The volume swell for Kalrez® Spectrum™ 0040 is approximately 10% when exposed to nitric acid at 110°C for 168 hours. Compression set resistance is similar to that of our broad chemically-resistant product, Kalrez® Spectrum™ 6375.
