Viton® A-401C fluoroelastomer is an incorporated cure "A-family" dipolymer designed for compression molding of sealing devices that must meet specific fluoroelastomer specifications. In addition to the heat and chemical resistance characteristics typical of Viton® fluoroelastomers, Viton® A-401C offers significant improvements in processing and rheology. Viton® A-401C can be blended with similar Viton® types to provide variations in processing, properties, and shrinkage.

Features Compared with Viton® E-60C, Viton® A-401C features:

• Fully precompounded

• O-ring curative level

• Improved compression molding

• increased mold flow

• easier mold release

• less mold fouling

• Improved extrusion

• Increased cure rate

• Improved compression set resistance

• Same mold shrinkage as Viton® E-60C

Applications Viton® A-401C is highly recommended for O-rings, extruded cord, gaskets, seals, and profiles. Viton® A-401C can be formulated to meet fluoroelastomer specifications Mil-R-83248B, AMS 7276D, and AMS 7259A.
