FKM Rubber Sheet
The Fluoroelastomer rubber sheet which exhibits excellent resistance to extreme temperatures, they also provide some of the best resistance to harsh chemicals like acids and alkalis. They also good resistance to petroleum-based oil and fuel like petrol, LPG or diesel.
They give resistance to mineral acids and aliphatic and aromatic hydrocarbons. They are also stable when exposed to harmful UV rays and therefore also resistant to the adverse effects of ozone. They are also virtually unaffected to weathering and is best suited for critical temperature sealing and corrosion protection applications.
