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.
