DuPont Mobility and Materials Kalrez® W230 Fluoroelastomer  (discontinued **)
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: DuPont™ Kalrez® W230 perfluoroelastomer parts are a black product for PV wet and select dry manufacturing processes requiring a wide range of chemical resistance. W230 provides an excellent combination of properties (resistance to acids/bases) and is the product of choice for wet PV processes as an upgrade from standard elastomers. A maximum continuous service temperature of 230°C is suggested.

Features/Benefits

  • Improved resistance / low volume swell in a wide range of wet chemistries (acids/bases)
  • Improved ozonated DI water resistance
  • Improved ozone and ammonia gas resistance
  • Low metals content
  • Improved resistance to a wide range of plasmas

Suggested Applications

  • Wet etch tools
  • Roller applications for wet inline tools
  • Wet chemical management systems
  • MOCVD and other select dry processes
