Tritan medical-grade polymers are designed to provide lipid and chemical resistance (important in hospitals where devices may be subjected to harsh cleaners, and in home care applications where the resin withstands cleaning in dishwashers), high heat stability, easy processing, clarity, durability, and toughness. Hanson said that Tritan is made without bisphenol-A (BPA) or halogens. He noted that the Food and Drug Administration was in the process of acquiring information about medical devices that may contain BPA.
Hanson added that Tritan resins are cost-competitive with acrylics and polycarbonates, and may be processed with the same tooling used for copolyesters. The company is looking into pharmaceutical applications for Tritan as well.
