DeWAL DW 230

  • Good Machine Direction Strength

  • Excellent Chemical Resistance

  • Low Coefficient of Friction

    • Low Coefficient of Friction

DW 230 is an unsintered PTFE (Polytetrafluoroethylene) film used primarily for wire and cable applications.

The polymer is fibrillated, giving good strength in the machine direction. It has 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.


DW 230 is used in cable for harness wrap and other wire and cable applications. 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. DW 230 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.
