UNMTM Waterproof and Breathable Membrane with Adhesive Backing
Widely used in automotive parts, outdoor lighting fixtures, communication equipment, pesticide and chemical packaging, plant protection tissue culture, connectors, new energy, and other fields.
High Performance
UNM ePTFE vent membrane has high porosity and uniform pore size, excellent breathability, low coefficient of friction, and low adsorption. It also possesses dustproof, oleophobic, hydrophobic, and heat-resistant properties, maintaining stable breathabilit
Highly Effective Dustproof
UNM ePTFE vent membrane utilizes surface filtration, resulting in a high dustproof rate. The surface is smooth, easy to clean, provides excellent barrier properties, and has a long lifespan. The adhesive-backed membrane is easy to install, supporting both
Pressure Balancing
Adhesive-backed products enhance waterproofing while maintaining breathability. Even with large pressure differences, they quickly balance pressure, preventing liquid penetration.
Overview
UNM Waterproof and Breathable Membrane Effectively controls internal pressure in mobile devices, outdoor electronic equipment housings, packaging, and automotive components—extending service life, improving equipment reliability, and preventing deformation that could lead to component failure.
