Texin® 983A

Texin 983A resin offers outstanding abrasion resistance, impact strength, toughness, and flexibility. It also exhibits excellent hydrolytic stability. Texin 983A resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), subject to the limitations of these and and other applicable regulations.Applications include belting, hose, seals and gaskets, tubing, cable jackets, hose jackets, athletic soles, casters, mine screens, film, and extruded profiles. As with any product, use of Texin 983A resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

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 983A resin must be thoroughly dried for a minimum of 4 hours in a desiccant dehumidifying hopper dryer to a moisture content of less than 0.03%. Hopper inlet air temperature should be 180°-200°F (82°-93°C), the inlet air dew point should be -20°F (-29°C) 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.

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.
