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.
