Viton® A-100

Viton A-100 fluoroelastomer is an ultralow-viscosity, "A-type" gum polymer that demonstrates improved processing and rheology in comparison with existing fluoroelastomers. Viton A-100 is especially designed for use with Viton Curative #50. It may be blended with other Viton types to enhance flow and processibility.

Compared with other "A-family" dipolymers, Viton A-100 provides:
-Ultralow viscosity
-Improved processing
-increased mold flow
-can be blended with other Viton types to enhance processibility and improve flow
-Excellent mold release
-Good compression set resistance for low-viscosity types of Viton

Applications
-Transfer and injection molding of complex shapes such as gaskets
-Extrusions
--can be used to modify viscosity of other types of Viton
-Solution coating
--fabric
--tanks or chemical containers
