Kynar Chemical Resistance Chart

Kynar Resin can be:
  • Extruded
  • Welded
  • Machined
  • Thermoformed
  • Injection Molded
  • Solubilized
  • Alloyed with Acrylics

There are over 20 grades of Kynar resins available inlcuding flexible copolymers. Contact SPS for more information.

In general, Kynar is chemically resistant to:
  • Most acids
  • Salts and weak bases
  • Halogens
  • Halogenated solvents
  • Alcohols
  • Fluids or gas streams in excess of 212F (100C)
  • Nuclear and UV radiation
  • Oxidants

Maximum Usage Temperatures for Kynar Resin with Selected Chemicals

Consult SPS if you have any questions or for more recent results.

  • Pre-substance unless otherwise indicated
  • Temperatures in °F have been rounded to °C in 5° increments
  • NR indicates that Kynar resin is not recommended for use with the chemical at room temperature or at the temperature indicated
  • The temperatures listed are a maximum value and so not take into account pressure, vacuums, mixtures, and close tolerances
