DeWAL DW 220      
Polytetrafluoroethylene      
Product Description:      
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. It's tensile strength is approximately 10% higher and the elongation is approximately 30% higher than for a standard homopolymer PTFE.
       
With its ability to be heat fused, this film finds applications in the convoluted PTFE hose industry as a inner liner material.
