Automotive Lights

Without the fragility and variability common in non-sintered materials, POREX Virtek® PTFE, which is specifically designed for exterior automotive lights, uses unique sintered material that outperforms competitive expanded materials. With its robust porous structure, our vents equalize pressure while minimizing humidity flow into the enclosure, protecting enclosure seals from premature failure. 

  • Resists entry of moisture, thus reducing moisture buildup and condensation
  • Repels water, dust, oil, and other automotive fluids 
  • Robust sintered structure allows for easy handling and assembly
  • Can be ultrasonic or thermally welded without cumbersome assembly steps
  • 100% free of PFOA – compliant with (EC) 1907/2006 REAC / Regulation (EU) 2019/1021 POP
  • Porex Virtek PTFE® 
  • Rolls, slit rolls, sheets, discs or adhesive backed shapes
