Description

Poly[4,4'-Methylenebis(Phenyl Isocyanate)-Alt-1,4-Butanediol/Poly(Butylene Adipate)] is a segmented polyurethane copolymer, specifically a thermoplastic polyurethane elastomer (TPU) synthesized from MDI, 1,4-butanediol, and a poly(butylene adipate) soft segment. This engineered polymer is valued for its unique combination of high elasticity, excellent abrasion resistance, and good chemical stability, making it a versatile material for demanding applications. It is primarily sought by manufacturers in the automotive, industrial machinery, and specialized consumer goods sectors seeking durable, flexible components.

Application

• Automotive Components: Used in the production of durable seals, gaskets, bushings, and under-the-hood parts requiring oil and fuel resistance.
• Industrial Rollers and Wheels: Ideal for manufacturing high-performance rollers, conveyor belt components, and industrial casters due to its abrasion resistance and load-bearing capacity.
• Wire and Cable Jacketing: Serves as a protective, flexible, and durable outer sheath for cables that require mechanical toughness and environmental protection.
• Technical Hoses and Tubing: Employed in hydraulic, pneumatic, and fluid transfer hoses where flexibility, pressure resistance, and compatibility with various fluids are critical.
• Sporting Goods and Footwear: Used in high-wear components of athletic equipment, shoe soles, and other items demanding resilience and flexibility.
• Industrial Belting and Films: Formulated into high-strength, flexible belts and specialty films for packaging or technical laminates.

Quality Control

Our production of this thermoplastic polyurethane adheres to strict batch-to-batch consistency protocols. Quality is verified through comprehensive testing of key parameters including intrinsic viscosity, hardness (Shore A/D), tensile strength, elongation at break, and thermal properties (DSC, TGA). Certificates of Analysis (COA) detailing these specifications are provided with every shipment to ensure the material meets your precise formulation and processing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be protected from atmospheric moisture to prevent property degradation. Keep away from strong acids, bases, and oxidizing agents.
