Fluoropolymer Compounds

Fluoropolymer Compounding

Melt processible fluoropolymers are a class of thermoplastic polymers where some or all of the hydrogen has been replaced by fluorine. The result is a fully fluorinated polymer or a partially fluorinated polymer.

General Fluoropolymer Advantages

  • High temperature performance and endurance
  • Outstanding chemical resistance
  • High purity
  • Excellent UV resistance
  • Low friction
  • Highly ductile to highly rigid materials
  • Opaque to clear materials
  • Good fatigue resistance
  • Colorable
  • Chemically inert
  • Excellent flame resistance
  • Sterilization
      – EtO – yes
      – Gamma – depends on material

Fluoropolymer Materials (Highly fluorinated)

  • FEP
  • PFA
  • MFA

Fluoropolymer Materials (Partially fluorinated)

  • PVDF
  • THV
  • ETFE

Fluoropolymer Additive Options

  • Radiopacifiers: Barium sulfate, Bismuth subcarbonate, Bismuth trioxide, Tungsten
  • Custom Colors: Pre-colors & concentrates

Foster Fluoropolymer Compounding

At Foster, all fluoropolymer compounds are manufactured using twin screw extrusion processing with corrosion resistant Hastelloy metal coating on all contact surfaces. Multiple down-stream feed ports allow for inputting raw materials at the appropriate stage in the extrusion process. Our range of feeding systems allow for handling pellet or powder ingredients. Programmable screw configurations ensure optimal mixing for both low volume sample development and high-volume manufacturing.
