Description

1,3-Benzenedicarboxylic acid, dimethyl ester, polymer with 1,4-butanediol, dimethyl 1,4-benzenedicarboxylate and .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) is a high-performance thermoplastic copolyester elastomer (TPC-ET) known for its excellent mechanical properties and chemical resistance. This material is engineered to deliver a unique balance of flexibility, durability, and processability, making it a superior alternative to conventional rubbers and other elastomers. It is primarily sought after by manufacturers in the automotive, industrial, and consumer goods sectors for demanding applications requiring long-term performance under stress and environmental exposure.

Application

• Automotive Components: Used in CVJ boots, air ducts, seals, and vibration dampeners due to its oil and heat resistance.
• Industrial Hose & Tubing: Ideal for hydraulic and pneumatic hoses, fuel lines, and industrial tubing requiring flexibility and chemical stability.
• Consumer Goods: Employed in sports equipment, wearable device straps, and tool grips for its durability and comfort.
• Wire & Cable Jacketing: Provides excellent protection as an insulating and sheathing material in demanding environments.
• Medical Device Components: Suitable for certain non-implantable medical parts where biocompatibility and sterilization resistance are required.
• Polymer Modification: Acts as a performance additive to enhance the toughness and impact resistance of other engineering plastics.

Quality Control

Our thermoplastic copolyester elastomer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Production adheres to relevant ISO standards, and material properties are verified against comprehensive specifications including intrinsic viscosity, melting point, and mechanical performance tests. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 material integrity. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
