Chemfluor® FEP Tubing

Chemfluor® tubings are made using fluoropolymers under strictly controlled processing conditions.

Chemfluor® fluoropolymer tubings have outstanding chemical and physical properties and can be used in a broad range of temperatures, from -400°F to 500°F, depending on the polymer type. Chemfluor® tubings are available in a variety of different polymer types including FEP, PFA and PTFE. The primary differences among them are use temperature, clarity and mechanical strength, while several chemical and physical properties are common to all. No plasticizers, stabilizers or fillers are used, so they are pure and non- contaminating. Unlike metal and rubber alternatives, Chemfluor® tubings are non-corroding and non- oxidizing. Unlike other plastic materials, they are unaffected by solvents, acids and fuels.

FEP is a fluoropolymer with excellent physical and chemical properties. It can withstand low cryogenic temperatures, and has low porosity and low permeation. Chemically inert at extreme temperatures, FEP can operate in temperatures ranging from -100°F to 400°F.

The material's transparency and weatherability make it ideal for use in sight gauges, especially when used with harsh chemicals.
