Description

1,4-Benzenedicarboxylic Acid Polymer With 1,2-Ethanediol, α-Hydro- ω-Hydroxypoly(Oxy-1,4-Butanediyl) And α-Hydro-ω-Hydroxypoly (Oxy-1,2-Ethanediyl) is a specialized thermoplastic polyester elastomer (TPEE) copolymer, engineered to deliver a unique balance of high-performance properties. This material is critical for applications demanding exceptional resilience, chemical resistance, and durability under a wide range of temperatures. It is primarily sought by manufacturers in the automotive, industrial components, and advanced materials sectors for creating flexible yet robust parts.

Application

• Automotive Components: Used in CVJ boots, airbag covers, and vibration-damping mounts due to its excellent fatigue resistance and performance across temperature extremes.
• Industrial Hose & Tubing: Ideal for hydraulic hoses, pneumatic tubing, and fuel lines where resistance to oils, fuels, and hydraulic fluids is required.
• Consumer Goods & Sporting Equipment: Employed in high-durability items like ski boots, smartwatch bands, and power tool housings for its flexibility and toughness.
• Electrical & Wire Insulation: Serves as a protective jacketing material for cables and wires, offering good dielectric properties and environmental stress crack resistance.
• Medical Device Components: Utilized in non-implantable medical parts requiring sterilization compatibility, flexibility, and strength.
• Polymer Modification: Acts as an impact modifier and compatibilizer in engineering plastic blends to enhance toughness and flexibility.

Quality Control

Our production of this thermoplastic polyester elastomer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, melting point, hard segment content, and mechanical properties are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing specific grade specifications is provided with each shipment to support your quality assurance protocols.

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 strong acids and organic solvents. For long-term storage, a nitrogen blanket is recommended to prevent oxidative degradation.
