Product description
Texin 987AU resin is an aromatic polyether-based thermoplastic polyurethane; it can be processed by injection molding, extrusion or blow molding.
Applications
Texin 987AU resin offers good clarity and outstanding abrasion resistance, impact strength, toughness, and flexibility. It is stabilized against degradation due to heat and UV exposure. It also exhibits excellent hydrolytic stability. Texin 987AU natural color resin is listed under NSF standard 61 for use in potable water applications. Typical applications include belting, hose, cable jackets, hose jackets, seals and gaskets, athletic soles, casters, mine screens, industrial components, tubing, film, and extruded profiles. As with any product, use of Texin 987AU resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
Storage time
Texin thermoplastic resins are hygroscopic and will absorb ambient moisture. The presence of moisture can adversely affect processing characteristics and the quality of parts. Therefore, the resins should remain in their sealed containers and be stored under cool and dry conditions until used. Storage temperature should not exceed 86ºF (30ºC). Unused resin from opened containers, or reground material that is not to be used immediately, should be stored in sealed containers.Prior to processing, Texin 987AU resin must be thoroughly dried in a desiccant dehumidifying hopper dryer for a minimum of 4 hours. Hopper inlet air temperature should be 180º-200ºF (82º-93ºC). To achieve the recommended moisture content of less than 0.03%, the inlet air dew point should be -20ºF (-29ºC) or lower. Where end-use requirements permit, up to 20% Texin resin regrind may be used with virgin material. Regrind material must be generated from properly molded/extruded parts, sprues, runners, trimmings, and/or films. Degraded or discolored material may not be used for regrind. All regrind material must be free of contamination and thoroughly blended with virgin material prior to drying and processing. Finish parts containing regrind must be tested to ensure that end-use requirements are fully met.
Processing
Typical starting conditions for injection molding, extrusion, and blow molding are noted below. Actual processing conditions will depend on machine size, mold design, material residence time, shot size, part geometry, etc.
