DeWAL DW 502      
Polytetrafluoroethylene      
Product Description:      
D/W 502 is a skived, tensilized PTFE (Polytetrafluoroethylene) film held to close tolerance on width and thickness. D/W 502 conforms to Mil-P-22241B. The tensilizing process yields a film with greatly enhanced tensile and dielectric strength.
       
D/W 502 finds use in electrical applications where high temperature service rating and superior electrical properties are desired. Examples of electrical applications include capacitor films, harnesses for electrical wiring in automotive and aerospace applications, spacers for transformers and other electrical insulation applications where high dielectric strength and high temperature resistance are requisite.
