Early engineers of Stronger Porous solutions

In 1961, Mr. Bob Dickey, a research scientist, started a small business making sheet material out of various polymers to be used in a caustic fluid separation process. At this time, the porous plastics industry was still in its infancy: Mr. Dickey and his two employees refined sintered porous plastics for commercial production purposes.

Porex Materials Corporation was incorporated on April 27, 1961, and, shortly thereafter, Mr. Dickey and his employees applied the technology they had developed to making the first porous plastic nibs for writing instruments. Launching a line of products under the POREX brand name, Porex quickly set the performance standard for writing nibs with sales reaching $1 million in 1968.

In the decades to follow, Porex garnered a leading presence in diverse markets including biomedical and life sciences, electronics, cosmetics and more. The unique properties of porous plastics materials combined with the groundbreaking design and engineering expertise of Porex employees fostered continued growth that spurred entrance into critical markets and led to key acquisitions. The company also grew internationally, expanding into Europe in the 1980s and to Asia in the 1990s. Most recently in 2018, Porex expanded within Malaysia and China to enhance operations and customer support.


In 2013, Porex became a member company of the Filtration Group.  Filtration Group is on a mission to make the world safer, healthier and more productive.  With a passionate workforce, global footprint and world class engineering and manufacturing capabilities, Filtration Group is driving innovation and developing solutions across a broad spectrum of applications in the fast-growing global filtration industry.
