| 3M™ Dyneon™ Fluoroplastic THV 500GX4Z is a fluorothermoplastic containing tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride. Because of its well-balanced profile of low temperature processing, low flammability, thermal stability and melt processability, this product should preferably be used for extruded film, profiles, wire coatings and tubes, for example in automotive fuel hoses. Due to its special composition it shows excellent performance with respect to dynamic testing. Special Features Excellent flexibility Excellent chemical resistance Excellent permeation resistance to fuels Bondable to itself and other substrates (for multi-layer constructions) Processing profile allows co-processing with olefinic plastics and hydrocarbon elastomers Low flammability High transparency Low refractive index&& |
