WILMINGTON, DEL. - DuPont Engineering Polymers has added crastin polybutylene terephthalate resins to its line of engineering resins, moving a product it acquired in 1993 from Ciba-Geigy AG to North American markets. DuPont, based in Wilmington, also is changing PBT resins now offered under the Rynite trade name to Crastin.
Henry Voigt, director of the Americas region for DuPont, said the new Crastin resins will round out DuPont's offerings.
"We have a broad crystalline (resin) portfolio. That is our focus," Voigt said in a March 17 interview, noting that a complete line of PBT resins was the only missing component of DuPont's portfolio.
DuPont had offered 10 grades of Rynite resins, but will now offer 19 grades of Crastin resins, said David Trerotola, marketing manager for crastin and Rynite resins.
The Crastin resins previously were made nad generally available only in Europe, although DuPont offered limited quantities to its North American customers.
With its PET and polycyclohexylenediemethylene terephthalate resins, DuPont claims it has the widest offerings of polyalkylene terephthalate resins in North America.
DuPont will make the PBT resins at its facility in Parkersburg, W. Va., and intends to unveil the new resins in North America throughout the year, Trerotola said. DuPont will offer reactorgrade and compounded resins in its Crastin line, which will include unreinforced, glass-reinforced, toughened, alloyed and flame-retardand products, he said.
DuPont plans to market the PBT resins primarily for applications in the electrical and electronic markets, Trerotola said.
DuPont also announced it intends to expand production of PBT resins at its facility in Uentrop, Germany. DuPont will add 66 million pounds of production capacity there by the middle of 1996.
