UNMTM Automotive Vent Membrane or Material for Exterior Lighting
Our product can help enhance component reliability and longevity by offering life-of-vehicle condensation reduction, pressure equalization and ingress protection for headlamp, rear lamp, fog lamp and accessory lamp assemblies.
Reduce Fogging
Our vents effectively reduce condensation in headlamps through continuing moisture diffusion, both when the vehicle is moving and when it’s parked.
Dustproof & Waterproof
They reliably keep out rain, sleet, snow, dust, dirt and debris, and withstand automotive fluids, detergents and washing products.
Balanced Pressure Relief
These breather patches continuously equalize pressure imbalances, to protect housing integrity in automotive exterior lighting.
Overview
Car lighting can be compromised by environmental challenges: Heating/cooling cycles or humidity — or even some plastic material used for car headlamps — can create condensation; pressure differentials can stress seals to failure; ingress of water, dust, debris, moisture or automotive fluids can degrade lens clarity or damage integrated electronics.
