Fluorosilicone O-Rings

Common Names
Fluorosilicone, FVMQ

Trade Name:  Silastic® LS,   FSE

General Description:

Fluorosilicone is a widely used elastomer that can be compounded to meet a wide range of applications.  The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuels and mineral oil resistance but poor hot air resistance when compared with silicone. This material is widely used in semiconductor Ashing equipment for its resistance to oxygen plasma.
