Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With 1,6-Hexanediol And .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) is a high-performance thermoplastic copolyester elastomer (TPC-ET) known for its exceptional combination of flexibility, durability, and chemical resistance. This engineered polymer is crucial for manufacturers seeking materials that can withstand demanding mechanical and environmental conditions while maintaining processability. It is primarily utilized in the production of advanced elastomeric components for the automotive, industrial, and consumer goods sectors.

Application

• Automotive Components: Used in CVJ boots, air ducts, seals, and hoses due to its excellent resistance to oils, greases, and temperature extremes.
• Industrial Hose & Tubing: Ideal for hydraulic and pneumatic hoses, fuel lines, and industrial tubing requiring flexibility and long-term fluid compatibility.
• Consumer Goods: Manufacture of durable goods such as sporting equipment, tool grips, and flexible phone cases.
• Wire & Cable Jacketing: Provides superior insulation, abrasion resistance, and flexibility for specialty cables.
• Medical Device Components: Suitable for non-implantable parts requiring repeated sterilization and chemical resistance.
• Polymer Modification: Acts as a performance additive to enhance the toughness and flexibility of other engineering plastics.

Quality Control

Our thermoplastic copolyester elastomer is produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as melt flow index, hardness, and thermal properties. Our quality commitment aligns with ISO 9001 standards, and materials can be supplied in compliance with REACH and other global regulatory frameworks as required.

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 and open flame. For long-term storage, maintain under a dry, inert atmosphere to prevent moisture absorption and thermal-oxidative degradation.
