Customizable water entry pressure (WEP) limits to withstand fierce external hydraulic loads and pounding rain storms.
Precisely tailored microporous sizing allowing free airflow while fully rejecting liquid water droplets.
Outstanding interception rating against micro dust, ambient pollen, and fine salt spray crystallization.
Pure fluoropolymer core completely immune to chemical destruction from acids, bases, or oxidative solvents.
The Micro-Porous Node Architecture
Our expanded PTFE structure contains billions of microscopic nodes per square centimeter. Since gas molecules are exponentially smaller than liquid water clusters, gas and vapor pass through effortlessly while liquid droplets remain physically barred outside.
Optional Oleophobic Wetting Defense
In environments with automotive engine vapors or packaging surfactants, liquids with low surface tension can clog standard membranes. Our specialized surface modification treatments increase surface energy resistance, preventing oil wet-out and pore blockages.
Thermal Stability & Adhesion Match
Ventrase membranes are built to handle structural processing. The material integrates flawlessly with various backings via heat-sealing, ultrasonic welding, or high-tack acrylic rings, maintaining its breathing properties even under heavy conversion stress.
Material Supply & Custom Configurations
We deliver our waterproof breathable media in multiple adaptable states to seamlessly suit your internal high-speed manufacturing lines.
Master & Slit Rolls
Available in customized slit widths. Ideal for high-output automatic manufacturing involving direct injection or punch welding.
ePTFE thermal fused onto woven polyester, non-woven polypropylene, or custom meshes for enhanced puncture resistance.
Adhesive-Backed Discs
Precision die-cut singular parts formatted on peel-and-stick liners, optimized for immediate hardware placement.
Unsupported Membranes
