According to the testing results of UL94, the product with the thickness of 152 microns offers VTM - 0 flame retardant performance, halide and no use of potentially harmful additives. It would also provide significantly better than that of flame retardant polypropylene puncture resistance and tensile strength, puncture proof performance is 3 times of flame retardant grade PP, the tensile strength is 2 times of flame retardant grade PP, and can adapt to the environment of high temperature. In addition, the standard of Elizabeth foundation innovation plastic film shrinkage resistance is 3 times of flame retardant grade PP. The product can also has low moisture absorption, high thermoplastic and excellent dielectric strength. And the product EFR735 membrane process is concise, can use thermoplastic, embossing, the whole die cutting, scribed line and bending process for processing.
