ETFE resin ETFE granule for injecting Random tower packing
ETFE has the advantage of both PTFE Powder and Polythene.
ETFE has perfect insulativity, thermo chemical, thermo to aging, radioresistance and easily to process. Also with well toughness, hardness, cold flow and creep deformation etc. ETFE has been widely used in aviation, spaceflight, semiconductor, petrochemical heavy-duty, seal material and solar industry.
ETFE has good chemical property:
A. aging resistance
B. radiation resistance
C. low permeability
D. high pressure resistance
E. oil resistance
F. anti-corrosion
polyvinylidene fluoride (PVDF), (perfluoroalkoxy polymer) PFA, Fluorinated ethylene propylene (FEP), ethylene-tetra-fluoro-ethylene (ETFE), Ethylene ChloroTriFluoroEthylene (ECTFE), Polytetrafluoroethylene (PTFE).
