Fluoropolymer Tubing

ETFE Tubing

ETFE tubing solutionsETFE is a fluoropolymer that is chemically and structurally similar to polyolefins such as polyethylene, thus providing a higher abrasion, impact, and crush resistance than its fully fluorinated (perfluoropolymer) counterparts -PTFE, FEP, and PFA.

ETFE tubing is commonly used in wiring harnesses, in exterior film applications where weathering resistance is desirable, and as a liner in tanks where specific chemical and wear resistance is required. Its high tensile strength at 25 C also leads to a higher working pressure at that temperature. ETFE’s mechanical and chemical properties were (and still are) so strong that it was chosen as a material for the Olympics! The Beijing National Aquatic Centre, built for the 2008 Summer Olympics, is the largest building made of ETFE laminate film.
