Viton™ A-700
Viton™ A-700, formerly called VTR-6769, is a gum fluoropolymer with a high viscosity compared to other A-type gum polymers. Viton™ A-700 is designed for use with Viton™ curative VC-50.
Viton™ A-700 fluoroelastomer is an A-type gum polymer composed of hexafluoropropylene (HFP) and vinylidene fluoride (VF₂).
Viton™ A-700 contains 66% fluorine content, is easy to process, and offers excellent physical properties. Viton™ A-700 is a high viscosity polymer best suited for compression molding applications.
Specifications
Physical Form: Pellets Appearance: Silver-gray, place amber Odor: None Nominal Viscosity, ML1 + 10 at 121 °C (250 °F): 74 Specific Gravity: 1.77 Storage Stability: Excellent Solubility: Low molecular weight esters and ketones
Primary Chemistry: Dipolymer of hexafluoropropylene and vinylidene fluoride
Features & Benefits
Excellent flow rate Easy mold release Resistance to mold fouling Improved compression set resistance Enhanced tear strength
Problems Solved
Processability and compatibility of fluoroelastomers and Viton gums in compression molding processes and applications Low resistance to compression set and high tear in rubbers and elastomeric applications
Applications
Fuel injector O-rings and rubber parts Compression molding of gaskets, O-rings, and seals Profile extrusions and calendared goods Extrusion applications of rubber and elastomers Can be blended with other gum polymers to alter the viscosity
