Product Description
Viton® A-200 fluoroelastomer is an "A-family" gum polymer that demonstrates improved processing when compared with existing fluoroelastomers. Viton A-200 is designed for use with the clean molding bisphenol curative, Viton Curative No. 50.

Compared to other "A-family" dipolymers, Viton A-200 provides:
-Lower viscosity
-Improved mold flow
-Excellent extrusion characteristics
-Better mold release
-Less mold fouling
-Improved compression set resistance

Applications:
-Transfer and injection molding
--O-rings
--Valve stem seals and shaft seals
--Parts with complicated shapes
-Extrusions
--Fuel hose and tubing
-Solution coating
--Fabric
--Tanks or chemical containers
