DW 330

DW 330 is a low density, premium grade extruded unsintered pure expanded PTFE product. It has the inherent benefits of PTFE: exceptional chemical resistance, extreme temperature range from -400 to +500°F(-240 to +260°C), low coefficient of friction, non-stick, along with excellent drape characteristics.


DW 330 low density PTFE is ideal for applications such as battery and fuel cell separators and gas sensor membranes. With outstanding chemical and thermal resistance, this film is well suited for harsh environments. The highly uniform pore structure allows this low density PTFE to perform successfully in critical venting situations. Excellent for close tolerance, splice free applications.
