Viton A-401C Fluoroelastomer Dupont Dow Elastomers Fluoropolymers SEALANT ADHESIVE In adhesives applications, Viton forms a strong bond that can flex without failure after repeated temperature cycling and vibration. Dipolymer of hexafluoropropylene and vinylidene fluoride, plus cure chemicals Viton A-401C fluoroelastomer is an incorporated cure “A-family” dipolymer designed for compression molding of sealing devices that must meet major 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. 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 Dipolymer of hexafluoropropylene and vinylidene fluoride, plus cure chemicals. Forms a strong bond that can flex without failure after repeated temperature cycling and vibration in adhesives applications.
