Description

1,4-Benzenedicarboxylic Acid,Dimethyl Ester,Polymer With 1,4-Butanediol And Decanedioic Acid is a high-performance thermoplastic copolyester elastomer (TPC-ET) known for its exceptional durability and flexibility. This engineered polymer is valued for its outstanding resistance to hydrolysis, thermal stability, and excellent mechanical properties, making it a superior alternative to conventional materials in demanding environments. It is primarily sought after by manufacturers in the automotive, industrial hose and tubing, electronics, and consumer goods sectors for creating robust, long-lasting components.

Application

• Automotive Components: Used in air ducts, bellows, constant velocity joint (CVJ) boots, and seals due to its high heat and chemical resistance.
• Industrial Hose & Tubing: Ideal for hydraulic and pneumatic hoses, fuel lines, and fluid transfer systems requiring flexibility and durability.
• Electrical & Electronics: Employed in protective cable jacketing, wire coatings, and connectors for its excellent insulating and mechanical properties.
• Consumer Goods: Used in sports equipment, appliance parts, and tool housings where impact resistance and weatherability are critical.
• Medical Device Components: Suitable for non-implantable medical tubing and device parts requiring repeated sterilization and biocompatibility.
• Polymer Modification: Acts as a performance additive to enhance the toughness, flexibility, and processing of other engineering plastics.

Quality Control

Our thermoplastic copolyester elastomer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including intrinsic viscosity, melt flow index, thermal properties (DSC), and mechanical performance to ensure consistent quality and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing all specifications are available upon request 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 polymer integrity. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which can affect processing.
