Chemours Viton® AL-300 with 2.5 phr Curative, 3 phr Ca(OH)2, and 6 phr High Activity MgO
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: Viton® AL-300 is an “AL-family” gum polymer that demonstrates improved processing when compared to its precursor Viton® B-70N. This gum provides:
  • Lower viscosity
  • Improved mold flow
  • Better mold release
  • Less mold fouling
  • Improved compression set resistance
  • Good low temperature characteristics

Applications:

  • Fuel systems, such as fuel injectors O-rings
  • Injection and transfer molding of O-rings, gaskets, and other sealing devices
  • Extruded cords, profiles and tubing, or calendered sheets, when a blend of gum polymers are used
  • Solution coatings of fabrics and other substrates

Information provided by manufacturer.

Chemours was formed from former DuPont performance chemicals businesses, including the Viton product line, in 2015.
