Description

1,4-Butanediol, polymer with 1,3-diisocyanatomethylbenzene and .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) Poly tetramethylene ether glycol polymer with 1,4 butanediol and 1,3-diisocyanatemethylbenzene CAS NO 9043-71-4 is a high-performance thermoplastic polyurethane (TPU) elastomer, synthesized from a polyether polyol, a chain extender, and an aromatic diisocyanate. This material is engineered to deliver an exceptional balance of mechanical strength, hydrolytic stability, and low-temperature flexibility, making it a critical component in demanding applications. It is primarily sought by manufacturers in the automotive, industrial machinery, and consumer goods sectors for producing durable, resilient parts.

Application

• Automotive Components: Used in the production of seals, gaskets, hoses, and cable sheathing due to its excellent abrasion resistance and performance across a wide temperature range.
• Industrial Rollers and Wheels: Ideal for manufacturing high-load-bearing rollers, conveyor belt components, and industrial wheels where toughness and durability are paramount.
• Hydraulic and Pneumatic Seals: Employed in dynamic sealing applications because of its good compression set resistance and compatibility with various fluids.
• Wire and Cable Jacketing: Provides flexible, durable, and protective insulation for cables requiring high mechanical and environmental resilience.
• Consumer Goods: Used in the production of high-performance shoe soles, sporting goods, and protective cases that demand a combination of flexibility and strength.
• Medical Device Tubing: Suitable for certain non-implantable medical tubing applications where its properties meet specific performance criteria.
• Adhesives and Sealants: Acts as a key raw material in formulating high-strength, flexible polyurethane adhesives and sealants.

Quality Control

Our thermoplastic polyurethane products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hardness (Shore A/D), tensile strength, elongation at break, and melt flow index are rigorously tested. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your technical 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). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect processing and final properties.
