Revenue model

1. Custom Porous Polymer Component Manufacturing: Porex designs and manufactures custom porous polymer components for customer applications. The revenue comes from engineering and manufacturing custom components tailored to specific device requirements across filtration, venting, absorption, wicking, diffusion, and application functions. Components are sold directly to manufacturers of medical devices, diagnostics, consumer goods, and industrial products who integrate them into their finished products.
2. Material Science Consulting and Co-development: Revenue generated through collaborative engineering partnerships where Porex provides material science expertise and co-develops solutions with customers from concept through production. This includes feasibility studies, prototyping, testing, and high-volume manufacturing services.

Core offering

Porex designs and manufactures custom porous polymer components and materials using four proprietary technology platforms (sintered porous plastic, bonded fiber, polyurethane open-cell foam, and porous membranes). The components serve functional roles of filtration, venting, wicking, absorption, diffusion, and application in life sciences, diagnostics, medical devices, consumer goods, industrial, and automotive end-products.

Product overview

Porex is a porous polymer material science company offering a portfolio of four proprietary technology platforms: Sintered Porous Plastic, Bonded Fiber (Porous Fiber Matrix), Porous Foam (Polyurethane), and Porous Membranes (including Virtek PTFE and track-etched membranes). These material platforms enable six core functional solutions—Absorption, Application, Diffusion, Filtration, Venting, and Wicking—served across four market segments: Life Sciences (Diagnostics, Medical Devices, Bioprocessing), Consumer Goods, Industrial, and Automotive. The company operates on a build-to-spec model, co-creating custom-engineered porous components with customers from concept through high-volume production, with ISO-certified manufacturing facilities worldwide.
