Description

1,4-Benzenedicarboxylic Acid, Polymer With 1,2-Ethanediol And .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) is a high-performance thermoplastic polyester elastomer (TPEE) known for its exceptional balance of flexibility, strength, and chemical resistance. This material is engineered to deliver superior durability and performance in demanding environments where traditional rubbers or plastics fail. It is a critical raw material for manufacturers in the automotive, industrial, and consumer goods sectors seeking to enhance product longevity and reliability.

Application

• Automotive Components: Used in CVJ boots, airbag covers, hose and tubing, and vibration dampening parts due to its excellent fatigue resistance and wide service temperature range.
• Industrial Hose & Tubing: Ideal for hydraulic hoses, pneumatic tubing, and fuel lines where resistance to oils, greases, and chemicals is paramount.
• Consumer Goods & Sporting Equipment: Employed in high-durability items like ski boots, watch straps, and protective phone cases for its resilience and flexibility.
• Wire & Cable Insulation: Serves as a high-performance jacketing material that protects against abrasion, weathering, and environmental stress cracking.
• Medical Device Components: Utilized in non-implantable medical parts requiring sterilization compatibility, flexibility, and strength.
• Polymer Modification: Acts as an impact modifier and compatibilizer to improve the toughness and flexibility of rigid engineering plastics like PBT and PET.

Quality Control

Our Thermoplastic Polyester Elastomer (TPEE) is manufactured under stringent process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive testing of key parameters including intrinsic viscosity, melt flow index, hardness (Shore D), and thermal properties (melting point, glass transition temperature). Certificates of Analysis (COA) detailing these specifications are provided with every 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 oxidizing agents and excessive heat sources to prevent degradation of polymer properties. For long-term storage, a nitrogen blanket is recommended to maintain optimal quality.
