Description

1,4-Benzenedicarboxylic Acid, Polymer With 1,4-Butanediol And .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) is a high-performance thermoplastic polyester elastomer (TPEE) block copolymer, renowned for its exceptional combination of elasticity, strength, and chemical resistance. This material is engineered to deliver superior durability and flexibility under demanding conditions, making it a critical component for advanced manufacturing. It is primarily sought by industries requiring robust materials for seals, hoses, automotive parts, and specialized cable jacketing.

Application

• Automotive Components: Used in CVJ boots, airbag covers, and vibration-damping parts due to excellent fatigue resistance and wide service temperature range.
• Industrial Hose & Tubing: Ideal for hydraulic hoses, pneumatic tubes, and fuel lines where oil, chemical, and abrasion resistance are paramount.
• Consumer Goods & Electronics: Employed in protective cases, wearable device components, and cable sheathing for its flexibility and toughness.
• Medical Device Components: Suitable for non-implantable parts requiring repeated sterilization and biocompatibility.
• Sporting Goods: Used in high-performance shoe soles, ski boots, and athletic equipment for its shock absorption and resilience.
• Polymer Modification: Acts as a compatibilizer or toughening agent to enhance the impact strength and flexibility of other engineering plastics.

Quality Control

Our thermoplastic polyester elastomer is manufactured under a strict quality management system. Each batch undergoes comprehensive testing for key parameters including intrinsic viscosity, melt flow index, hardness (Shore D), and thermal properties (melting point, glass transition temperature) to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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 oxidizing agents and excessive heat sources to maintain polymer integrity. The material is hygroscopic (moisture-sensitive); keep original packaging sealed until use.
