產(chǎn)品說明

D/W 2000 is a skived PTFE (Polytetrafluoroethylene) film held to close tolerance on width and thickness. D/W 2000 conforms to ASTM D 3308 Type II as well as to SAE AMS 3662C.

D/W 2000 finds use in electrical applications where high temperature service rating and/or superior electrical properties are desired. This material is often used as a release film in the production of high temperature flex circuit materials as well as in the production of microwave circuit materials where it is seen as both a release film and a bonding film. D/W 2000 is an excellent release film for the molding of composite structures.
