Viton™ FWRD Peroxide Curable APA Polymers

Superior Mechanical Properties and Aqueous Fluid Resistance

Viton™ FWRD fluoroelastomers made with Advanced Polymer Architecture (APA) dramatically improve processing characteristics, such as flow, cure, and mold release. Now produced without a fluorinated surfactant, these fluoroelastomers deliver the performance you expect while enabling continued supply in the face of an evolving regulatory landscape.

Viton™ FWRD APA Fluoroelastomers

Engineers and parts manufacturers specify Viton™ FWRD APA fluoroelastomers for the most demanding applications due to their high-temperature performance and exceptional chemical resistance.
