FEP Tubing

FEP Tubing

 

(Fluorinated Ethylene Propylene)

Polyflon offers FEP tubing in IDs ranging from 0.2mm up to 100mm and due to FEP being melt processable, very long continuous lengths are possible. Excellent chemical resistance, surface smoothness, transparency and purity of FEP tubing make it the material of choice in many fluid handling applications within the semiconductor, chemical process plant, instrumentation, bio-tech and medical markets.

Key Features of FEP Tubing:

  • Good optical clarity (96% UV transmission)
  • Very smooth internal surfaces
  • Reduced gas diffusion
  • Excellent chemical resistance
  • Ideal for thermoforming
  • Wide temperature range -254°C (-425°F) to 205°C (392°F)
  • Tight dimensional tolerances
  • Biocompatible
  • FDA & USP Class VI compliant
  • Gamma & ETO sterilisable

Availability of FEP Tubing:




Although the size range below satisfies most applications, many more sizes and custom dimensions are possible to suit your specific needs.
