In July 2008, Poco Graphite Inc was acquired by Entegris, and became a wholly-owned subsidiary. Poco Graphite works in the consumable component market with high-quality products that meet the changing needs of OEMs and semiconductor manufacturers. POCO's 40-year history of material research and development continues to produce unique materials targeted at specific applications. Man's desire to explore space and safely return led to the development of specialty materials that could withstand high temperatures during reentry. One of these materials in the race to conquer space was a specialty graphite developed by a Texas based aerospace company. Because an alternate material was selected for this application, this unique technology was sold to Pure Oil Company in 1964. This graphite division became known as POCO, an acronym for the new owner. POCO's specialty graphites finally made it to outer space in 1977. This material was used in the radioisotope thermoelectric generators onboard Voyager I and Voyager II. POCO materials are used in many diverse applications and industries. POCO products are produced for the following major markets: Semiconductor and general industrial products, biomedical, glass industry products and electrical discharge machining (EDM). As a producer of highly technical materials, POCO offers exceptional customer support, including specific application information, design capability, machining and materials testing.
