Extruded ETFE Wires (Ethylene tetrafluoroethylene)

ETFE Fluoropolymer are melt processible Thermoplastics which is distinguished from perfluopolymers (totally fluorinated polymers) as a partially fluorinated copolymer of ethylene and TFE. This chemical modification provides significantly higher strength relative to PTFE, FEP or PFA. It is less flexible than PTFE, but has superior impact strength, abrasion and cut through resistance. Addition of a third component to the chemical structure creates a modified ETFE that has lower weight per unit volume, is stiffer and tougher than PTFE, PFA or FEP.

These properties allow it to withstand greater physical abuse during its lifetime. The material is good for use as a dielectric - it has a dielectric constant of 2.6, a high dielectric strength, excellent resistvity and a low dissipation factor of magnitude 0.003. Its low dielectric constant is essentially constant with changing frequency or temperature. It has a broad and useful temperature range, usually set to -65ºC to +150ºC continuously, it retains remarkable toughness at very low temperatures and the embrittlement temperature of ETFE is below -100ºC. In addition to this, ETFE passes several severe flame tests, for example IEEE 383 and has also the UL 94 V-0 rating. ETFE is Weather resistant, inert to most solvents & chemicals. ETFE has substantially better resistance to Radiations compared to any other fluorocarbon plastics is less immune to damage by long term exposure to Electron beam & gamma radiations, especially at elevated temperatures.
