CHARACTERISTICS: Rigid, Toughness, dimensional stability, biocompatiblity, and chemical resistance. Quadraplast™ is a family of aromatic rigid thermoplastic polyurethanes that are designed for injection molded biostable applications such as connectors, fittings, luers, and hubs. Quadraplast offers a unique combination of toughness, dimensional stability, biocompatiblity, and chemical resistance. Quadraplast is typically used to replace nylon and polycarbonate based engineered plastics where coloring or stress cracking may be an issue.
