Texin RxS285 resin is an aromatic polyester-based thermoplastic polyurethane. It can be processed by injection molding, extrusion or blow molding.
Product description
Applications
Texin RxS285 offers outstanding abrasion resistance, impact strength, toughness and flexibility. Typical medical applications include dental ligature, tubing and luers. As with any product, the use of Texin RxS285 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
Storage
Texin thermoplastic polyurethane resins are hygroscopic and will absorb ambient moisture. The resins should remain in their sealed containers and stored in a dry area. Storage temperatures should not exceed 86°F (30°C). Unused resin from opened containers, or reground material that is not to be used immediately should also be stored in sealed containers under cool and dry conditions.Prior to processing, Texin RxS285 resin must be thoroughly dried for a minimum of 2 hours in a desiccant dehumidifying hopper dryer to a moisture content of less than 0.03%. Hopper inlet air temperature should be 180-210°F (82-99°C), the inlet air dew point should be 0°F (-18°C) or lower.
Processing
Typical starting conditions for injection molding, extrusion and blow molding are noted below. It is recommended that initial processing is done at the lower end of the suggested temperature ranges and increased as necessary. Actual processing conditions will depend on machine size, mold design, material residence time, shot size, part geometry, etc.
