Product Description
Viton A-500 fluoroelastomer is a new generation "A-family" gum polymer that provides improved processing when compared with existing fluoroelastomers.

Viton A-500 is designed for use with the clean molding bisphenol curative, Viton Curative No. 50.

Compared to "A-family" dipolymers, Viton A-500 provides:
-Improved compression molding
-Better mold release
-Less mold fouling
-Faster cure rate
-Improved compression set resistance

Applications
-Compression and transfer molding
--O-rings
--gaskets
--seals
-Profile extrusion
-Calendered goods
