Can be directly ultrasonic or thermally welded to plastic enclosures, creating a permanent bond. Restricts moisture vapor transmission, which results in less humidity entering into the enclosure during cooling, thereby reducing potential condensation issues. Automotive Lighting Vents Minimize headlight condensation LEARN MORE Electronic Enclosure Vents Protect electronic enclosures with sintered PTFE material LEARN MORE Automotive Lighting Vents Optimize headlight performance Without the fragility and variability common in non-sintered materials, POREX Virtek PTFE is a unique sintered material that outperforms competitive expanded materials. With its robust porous structure, our vents equalize pressure while minimizing humidity flow into the enclosure and protects enclosure seals from premature failure. Specifically designed for exterior automotive lights, our vents: Reduce moisture buildup and condensation– POREX Virtek resists the entry of moisture into the headlight enclosure, thus lowering the risk of condensation on the headlamp lens. Stop contaminants from entering enclosure–POREX Virtek sintered material repels water, dust, oil and other automotive fluids. Assemble easily–Very robust sintered structure allows easy handling and can be ultrasonic or thermal welding without cumbersome assembly methods.
