CHASKA, Minn., July 15, 2009 (GLOBE NEWSWIRE) -- Entegris, Inc. (Nasdaq:ENTG) announced today that it has entered into a marketing and co-branding agreement with Victrex USA, Inc. The agreement centers on Entegris' TEGO^™ polymers with carbon nanotubes using VICTREX^® PEEK^™ polymer. Already proven for the semiconductor industry, TEGO polymers are now available for expanded customer use in other growing markets, including medical, aerospace, automotive, industrial, and oil and gas. Applications for use of TEGO polymers include films, cabling, tubing, gears and heat management.

"We are excited to enter into this agreement with Victrex, a relationship that should create new opportunities for both companies and our customers, as well," said Shawn Cheesman, general manager, TEGO polymers, Entegris. "Expanding the availability of TEGO polymers to other industry applications will help generate innovative solutions resulting in new customer uses."

Entegris' focus on TEGO composite development includes high-value polymers that contain carbon nanotubes for increased thermal and electrical conductivity, as well as tensile strength. The company invested several years of research into developing processes that achieve excellent dispersion of carbon nanotubes into composites. A compounder has to get good dispersion in the polymer in order to reap the benefits of using carbon nanotubes over other carbon compounds.

Additionally, the company has developed proprietary technology for the dispersion of nano-scale materials into VICTREX PEEK and other thermoplastics. Well-dispersed carbon nanotubes in a polymer, like VICTREX PEEK, provide consistent electrostatic discharge (ESD) and improved thermal stability.

"We are very pleased to support Entegris' TEGO polymers as the next generation of carbon nanotubes based on VICTREX PEEK polymer," said Michael Sandeen, technical leader, Victrex. "We have a long-standing relationship with Entegris and believe in the high quality of its product offerings. This agreement is an excellent opportunity for us to help promote the unique and optimized set of physical properties associated with TEGO polymers."
