Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With 1,2-Ethanediol is a high-performance engineering thermoplastic polymer, widely recognized by its common name, polyethylene terephthalate (PET). This material is valued for its exceptional combination of mechanical strength, thermal stability, excellent barrier properties, and clarity. It is a critical raw material for manufacturers in the packaging, textile, and engineering plastics industries seeking reliable, high-quality polymer resins.

Application

• Bottle Manufacturing: Primary material for producing clear, strong, and lightweight carbonated soft drink (CSD) bottles, water bottles, and food containers.
• Packaging Films: Used to manufacture biaxially oriented PET (BOPET) films for flexible packaging, lamination, and metallization applications.
• Textile Fibers: Spun into polyester fibers for clothing, home furnishings, industrial fabrics, and tire cord.
• Thermoforming Sheets: Processed into APET (amorphous PET) sheets for blister packs, clamshells, and food trays.
• Engineering Plastics: Reinforced with glass fibers to produce high-strength, dimensionally stable components for automotive and electrical applications.
• Strapping and Monofilaments: Manufactured into high-tenacity strapping for palletizing and monofilaments for industrial brushes and screening.

Quality Control

Our PET polymer is manufactured under strict quality management systems. Each batch undergoes comprehensive testing for key parameters including intrinsic viscosity (IV), color, melting point, and residual acetaldehyde content to ensure it meets the stringent requirements for bottle-grade, film-grade, or fiber-grade applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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 open flames and heat sources. As a hygroscopic material, it should be protected from excessive moisture to prevent hydrolysis and IV drop during processing.
