DuPont buys some Eastman polyesters. (Your Business in Brief).

DuPont Engineering Polymers in Wilmington, Del., has purchased a portfolio of high-performance polyesters from Eastman Chemical Co., Kingsport, Tenn. Product lines covered by the deal are Eastman's liquid-crystal polymer (Titan LCP), PCT polyester (Thermx PCT), and reinforced PET compounds (Thermx EG). DuPont says these materials broaden its existing offerings for automotive and electrical-electronic sectors.

Paul Kalicky, DuPont's v.p. of strategic planning, says the acquired Eastman LCPs are being incorporated into DuPont's Zenite LCP product line. According to Kalicky, Eastman LCP materials crystallize more slowly than DuPont's current products, translating into higher toughness and weld-line strength for thin-wall connectors and circuit boards processed at elevated temperature.

Thermx PCT materials give DuPont a specialty polyester with heat resistance beyond that of its Crastin PBT and Rynite PET lines. PCTs have HDTs from 482 to 532 F @ 66 psi.

DuPont also acquired Eastman's PCTA resin, a modified PCT that has approval for direct food contact (e.g., in housewares). DuPont plans to incorporate the Thermx glass-reinforced PET compounds into its Rynite line.
