| Kingsport, Tenn.(November 28, 2007) – Eastman Chemical Company announces the launch of Eastman Tritan™ copolyester.This new-generation copolyester offers a new level of flexibility and creativity for designers, brand owners and molders of commercial and consumer housewares.
Ideal for a range of molded housewares applications, including food storage containers, plastic utensils and barware, and sports bottles, Tritan combines the clarity, toughness and chemical resistance of traditional copolyesters with higher heat resistance and faster processing.This unique balance of properties can enable brand owners to provide consumers with products that have distinct designs and improved durability.
"Our proprietary new-generation copolyester addresses growing market needs for materials that can offer designers and brand owners differentiated product performance,” says Randy S. Beavers, business development manager, Specialty Plastics Business Organization, Eastman Chemical Company. “This new material draws from Eastman’s history of technical expertise and underscores our commitment to addressing market needs with innovative products.”
The unique chemistry of Tritan provides a higher glass transition temperature (Tg) than traditional copolyesters. This new-generation copolyester can also be molded into various housewares applications without incorporating high levels of residual stress. Combined with the material’s outstanding chemical resistance and hydrolytic stability, Tritan molded housewares enhanced durability in the dishwasher environment, which can expose products to high heat, humidity and aggressive cleaning detergents. In testing, this new-generation copolyester was able to withstand hundreds of cycles in residential and commercial dishwashers without cracking or crazing. This benefit can help brand owners significantly enhance consumer satisfaction and foster brand loyalty.
Tritan offers faster processing rates than traditional copolyesters and, due to potentially lower residual stress and outstanding chemical resistance and hydrolytic stability, it can be molded without requiring a secondary annealing process. These advantages can allow molders to use less energy and reduce related costs.
Tritan also has a two percent lower density than polycarbonate, which translates into more parts per kilogram, contributing to further cost savings. In addition, this new-generation copolyester can be used in molds designed for traditional transparent polymers, such as polycarbonate. This attribute provides processors with more material options to meet diverse customer requirements. |
