产品说明

A Skived PTFE Film that is produced from a modified homopolymer PTFE resin containing <1% of a fully fluorinated comonomer. The incorporation of the comonomer yields a material with improved electrical and physical properties. This film can be thermally fused to itself. The modified homopolymer resin exhibits chemical resistance equivalent to that of a standard homopolymer PTFE. Its tensile strength is approximately 10% higher and the elongation is approximately 30% higher than for a standard homopolymer PTFE. This product has been Sodium Ammonia etched for bonding.

With its ability to be heat fused, this film finds applications in the convoluted PTFE hose industry as an inner liner material. This materail is also an excellent candidate for diaphram applications.
