Porous Products
POR-TEK
POR-TEK is a microporous film produced from Ultra High Molecular Weight Polyethylene . The process yields a material with highly uniform pore structure in the X, Y and Z directions.
Application Information
POR-TEK has an open cell (tortuous path) structure with a void volume of 30 % to 50%. The material can be rendered hydrophilic through surface treatments and by plasma surface modification. Application areas include gas and liquid filtration, medical diagnostic test kits, wicks, low dielectric constant wrap for microwave cables, batteries and other applications where porosity, inertness, toughness and accuracy of gauge are important.
