The majority of the products manufactured and sold by Porex are molded products. These products fall into the custom product category. Custom products are produced from captive production tooling - so production rights belong exclusively to the owner of the production tool. Porex designs and manufactures custom components to meet specific customer requirements. Porex products are engineered from various polymers with controlled pore sizes to provide superior strength, durability, chemical resistance, resiliency and design flexibility. Porex's proprietary manufacturing techniques give us the ability to fabricate porous plastic materials into dimensional shapes, meeting very specific design engineering needs. Our filters, vents, wicks, membranes, diffusers and other media support components serve a range of applications with solutions designed to give you distinct advantages.
