This information is believed to be reliable, but no representation, guarantees or warranties of any kind are made to its accuracy or suitability for any purpose.  The information is based on laboratory testing and does not necessarily indicate end-product performance.  It is recommended that users conduct their own evaluations to determine suitability for the intended application.

Description: Excellent resistance to almost all chemicals. Excellent outgassing performance in vacuum environments.

Limitations:
Avoid low-molecular-weight, fully halogenated fluids and molten alkali metals.
Especially strong oxidizing acids may cause some swelling.  Helium permeability is slightly higher than fluoroelastomer compounds. Specific Simriz® compounds provide better low-temperature performance and amine resistance.

Chemistry:
Copolymer of tetrafluoroethylene and perfluorovinyl ether.
