產(chǎn)品說(shuō)明

D/W 203 is an unsintered PTFE (Polytetrafluoroethylene) film used primarily for electrical insulation, particularly for wire and cable applications. The polymer is fibrilated giving good strength in the machine direction. It has the inherent benefits of PTFE: exceptional chemical resistance, extreme temperature range from 450F to +500F, low coefficient of friction, excellent drape characteristics and non-stick properties.

D/W 203 is used in cable insulation, harness wrap, and as the dielectric medium in coaxial cables. Once sintered, it seals completely to provide excellent electrical insulating properties, unsurpassed chemical resistance and excellent thermal resistance. DeWAL's unsintered PTFE tape has good drape characteristics allowing it to conform smoothly to complicated shapes. D/W 203 can be used for gaskets, expansion joints, valve seals and diaphragm applications. It is available unpigmented and pigmented to match EIA colors. It has good strength after sintering and is used where chemical inertness and high temperature resistance are needed.
