What is ETFE and ETFE Rod?
ETFE (Ethylene Tetrafluoroethylene) is a super engineering plastic that combines exceptional mechanical strength with outstanding chemical resistance. Unlike traditional fluoropolymers, ETFE offers superior tensile strength, excellent transparency, and remarkable radiation stability, making it the preferred choice for demanding aerospace, chemical processing, and electrical applications.
ETFE rod provides the essential raw material. This semi-finished form of Tefzel® ETFE polymer is supplied as solid round bars or rectangular stock, specifically designed for turning, milling, and drilling into high-performance parts like valve seats, pump gears, and chemical processing equipment. Unlike thin films used for enclosures, our ETFE rod offers the substantial cross-section needed for structural integrity and complex machining.
