FINALLY, A KYNAR® GRADE FOR SEALS, O-RINGS, AND DIAPHRAGMS

Kynar UltraFlex™ is an elastomeric material based on Arkema's proven PVDF (polyvinylidene fluoride) resin. This unique fluoropolymer exhibits exceptional resistance to chemicals, ozone, ultraviolet light, radiation and moisture. Molding is very similar to many fluoroelastomers without the use of curing agents and molding time is significantly reduced. Post-curing of molded parts improves mechanical properties and chemical resistance.

PVDF Elastomers
  • Clear Elastomeric Fluoropolymer
  • Not Affected by UV or Radiation
  • Weatherable
  • Water Repellent
  • Broad Chemical Resistance
  • No Curing or Cross-Linking Agents
  • No Shelf Life for Feed Stock

Chemical Resistance

Chemical Resistance

 N/A Kynar® resins demonstrate excellent resistance to an extensive array of chemicals. They resist attack from most inorganic acids and alkalis, aliphatic and aromatic hydrocarbons, organic acids, alcohols and halogenated solvents. However, strong alkalis (i.e. pH >12) and strong polar solvents such as acetone, ethyl acetate, dimethylformamide and dimethylacetamide can impede the effectiveness of Kynar® resins.
