Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With Decanedioic Acid And 1,2-Ethanediol is a high-performance copolyester, commonly known as a modified PET (polyethylene terephthalate) copolymer. This engineered polymer is valued for its enhanced flexibility, impact resistance, and thermal stability compared to standard PET, making it a superior material for demanding applications. It is primarily sought by manufacturers in the packaging, specialty fiber, and engineering plastics industries seeking to improve product durability and processing characteristics.

Application

• High-Performance Packaging Films: Used to produce biaxially oriented films (BOPET) with improved toughness and clarity for food, pharmaceutical, and industrial packaging.
• Specialty and Technical Fibers: A key raw material for manufacturing industrial fibers requiring enhanced strength, dimensional stability, and chemical resistance.
• Engineering Plastics and Resins: Serves as a base polymer or modifier in compounds for automotive components, electrical connectors, and consumer durable goods.
• Hot-Melt Adhesives and Coatings: Imparts excellent adhesion and thermal properties to formulations for textiles and industrial bonding.
• Beverage and Food Containers: Used in the production of modified PET bottles and containers that require improved stress-crack resistance.
• 3D Printing Filaments: A component in specialized polymer blends for fused deposition modeling (FDM) filaments demanding specific mechanical properties.

Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency for industrial applications. Key parameters such as intrinsic viscosity (IV), melting point, copolymer composition, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee the material meets your processing and performance requirements.

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 heat sources and open flames. As a polymeric material, prolonged exposure to high humidity should be avoided to prevent any potential hydrolysis or property changes.
