Texin 255D resin is a polyester-based thermoplastic polyurethane with a Shore hardness of approximately 55D*. It can be processed by injection molding; extrusion processes are not recommended.
Properties / Applications
Texin 255D natural color resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), for use in articles that contact food except articles used for packing or holding food during cooking, subject to the limitations of these and any other applicable regulations.
Texin 255D resin offers excellent fuel and oil resistance, as well as outstanding abrasion resistance, impact strength, toughness, and flexibility. Typical applications include toplifts, seals, gaskets, sleeves, casters, and gears. As with any product, use of Texin 255D resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
