Advanced Porous Polymer Material Science Expertise

For over 60 years, Porex has applied our extensive porous polymer material science, product design, and custom plastic manufacturing expertise to developing custom-engineered porous solutions that help you address complex product development challenges and accelerate product launches. With our proprietary porous polymer technologies, we design and produce advanced porous materials exhibiting a broad range of thermal, chemical, and mechanical properties. In complex situations with multiple functional requirements, our development engineers will find the right technical solution using our expansive portfolio of materials and technology platforms. 

Different Types of Porous Technologies

Explore the five different types of proprietary porous technology platforms that our engineers leverage to design and manufacture custom porous components for your products.

Sintered Porous Plastics

Engineered from various polymers with controlled pore sizes to provide outstanding strength, durability, chemical resistance, resiliency, and design flexibility across multiple applications.

Porous Fiber

Fibers are bonded together to create two-dimensional cross-sections and extruded to create three-dimensional shapes.  A blend of polymeric fibers bonded together for ideal fluid handling capillary structures.

Porous Foam

A two-step pre-polymer process that uses customized blends of raw materials through a clean polyurethane process without the use of catalysts offers a wide range of softness, densities, and porosities.


Variety of porous membrane solutions that use controlled processes to ensure consistent and repeatable pore structures, including sintered PTFE, Oxyphen track-etched, and PES membranes.
