Exton, Pennsylvania -- Cray Valley's Hydrocarbon Specialty Chemical division has gained approval for a 40-percent capacity rise at its plant making Poly bd hydroxyl-terminated polybutadienes at Channelview, Texas. The company did not reveal its capacity for Poly bd, nor any financial details of the expansion.
The additional capacity is expected to be online by September 2011, said Cray Valley.
Polybutadiene polyols typically react with isocyanates to produce high-performance urethanes, used in adhesive and sealants, encapsulants, coatings and other speciality applications. Cray Valley says the polyols provide low-temperature flexibility, resistance to strong acids and bases, superior electrical properties and a low moisture transmission rate.
Cray Valley's other hydroxyl-terminated polybutadiene product, Krasol, is manufactured in the Czech Republic.
The Cray Valley USA llc business, based in Exton, Pennsylvania., is part of Total's Resins Division, one of the largest resin manufacturers in the world with sales of Euro 1900 million ($2500 million) and 3800 employees worldwide.
Its Hydrocarbon Specialty Chemical division provides hydrocarbon resins, Norsolene and Wingtack tackifying resins, along with Poly bd, Ricon, Krasol, SMA resins and Saret rubber coagents. These products are used as raw materials for adhesives, rubber and other applications.
