DW203

PRODUCT DESCRIPTION
DW 203 is an unsintered PTFE (Polytetrafluoroethylene) film used primarily for electrical insulation, particularly for wire and cable applications. Available unpigmented and pigmented to match EIA colors, the polymer is fibrillated, giving good strength in the machine direction.

Our unsintered PTFE film provides all of the inherent benefits of PTFE: exceptional chemical resistance, extreme temperature range from –450°F to +500°F, low coefficient of friction, excellent drape characteristics and non-stick properties.

APPLICATION INFORMATION
DW 203 is used in cable insulation and 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. Its good drape characteristics allow our unsintered PTFE film to conform smoothly to complicated shapes. DW 203 can be used for gaskets, expansion joints, valve seals and diaphragm applications, especially where chemical inertness and high temperature resistance are needed.
