FEP Tubing

About FEP Tubing

Polyflon offers FEP tubes in IDs ranging from 0.2mm up to 100mm and due to FEP (Fluorinated Ethylene Propylene) 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.
