Bayer Corp. has commercialized a new extreme-temperature grade of polycarbonate in North America. The Pittsburgh-based firm also recently had two of its materials selected for new medical applications.
The new grade of Bayer's Makrolon-brand PC is aimed at temperature extremes. Extreme cold applications for the material include storage containers, ski-boot buckles and snowmobile visors; while extreme heat uses include lamp and lighting components.
The new grade has been commercial in Europe since 2001 but just became available in North America this year. The grade is produced at a Bayer plant in Antwerp, Belgium.
On the medical front, Gish Biomedical Co. now is using Bayer PC in its Vison Blood Cardioplegia system. The system is used in cardiac surgery to warm and cool blood. Gish, based in Rancho Santa Margarita, Calif., selected the material because of its structural strength, biocompatibilty and clarity, Bayer officials said.
TRS Inc. also is using a grade of Bayer's Desmopan-brand aliphatic thermoplastic polyurethane on the gripping surface of a new prosthetic hand product. The material provides a soft grip and color stability and will allow the prosthetic to grip anything from an egg to a sledgehammer, according to Bayer.
Boulder, Colo.-based TRS was formed in 1979 by Bob Radocy, who lost his left hand in a 1971 auto accident.
