Eastman Chemical Company Announces New Thermx Automotive-Grade PolymersKINGSPORT, Tenn., Sept. 27 -- Eastman Chemical Company today introduced two new proprietary PCT (polycyclohexylene dimethylene terephthalate) engineering resins, Thermx CG033 and Thermx CGT33, targeted toward high-temperature connectors for the automotive industry Paul M. Flynn, electrical/electronics business segment manager for Eastman's specialty plastics business, said, "These new PCT polymers will fill the automotive market's need for a polymer with higher thermal stability to replace PBT, nylon 6 and nylon 66. Now designers of automotive connnectors can upgrade from these materials to Thermx PCT for applications requiring surface mount technology, through-hole reflow assembly, improved dimensional stability or for under-hood applications requiring improved heat stability." Thermx CG033 and CGT33 offer significantly higher heat deflection temperatures (HDTs) of about 260 degrees C when compared with PBT, which has an HDT of 205 degrees C. Thermx CG033 and CGT33 offer better cycle times, about 30% faster than previous PCT formulations. In addition, Thermx CGT33 offers enhanced toughness and impact resistance comparable to PBT. Eastman Chemical Company is the world leader in the manufacture of polyester plastics for packaging and other applications, including Thermx PCT, PET and LCP formulations. Eastman, based in Kingsport, manufactures and markets chemicals, fibers and plastics and had 1998 sales of $4.48 billion. The quality systems of all Eastman plastics are registered under ISO 9000 except at plants in operation less than one year.
