Material Notes:
Ethylene-Chlortrifluorethylene exhibits an extraordinary impact strength at temperatures ranging from -76°C to 150°C. A great part of the product properties attributes to the very smooth surface and differentiates HALAR® from other fluoropolymers. Due to the fact that ECTFE is very pure, this material is being used to process chemicals and ultrapure water for the semiconductor industry. Also, the permeation resistance to oxygen, carbon dioxide, chlorine gas and hydrochloric acid is 10 to 100 times better than PTFE.Propertiesextremely high impact strengthgood insulation propertiesvery good weather resistancehigh resistance to radiationvery high chemical resistancevery good sliding propertiesphysiologically harmlesshigh densitynon-consistent against hot aminesApplications includes parts which come in contact with aggressive materials, lining of tanks, pumps, flanges, fittings, parts in centrifuges and control engineering industry.
