Description

1,4-Benzenedicarboxylic Acid, Polymer With 1,2-Ethanediol is a high-performance engineering thermoplastic polymer, widely known as Polyethylene Terephthalate (PET). This material matters for its exceptional combination of mechanical strength, thermal stability, and excellent barrier properties against gases and moisture. It is a critical raw material for manufacturers in the packaging, textile, and engineering plastics industries seeking reliable, high-quality polymer resins.

Application

• Beverage & Food Packaging: Primary material for the production of clear, strong, and lightweight bottles for water, soft drinks, and edible oils.
• Thermoforming Sheets: Used to create clamshells, trays, and blister packs for consumer goods and food products.
• Textile Fibers (Polyester): Spun into filaments for clothing, home furnishings, carpets, and industrial fabrics due to its durability and wrinkle resistance.
• Engineering Plastics: Reinforced with glass fibers to produce components for the automotive and electrical industries requiring high strength and dimensional stability.
• Film & Packaging: Manufactured into biaxially oriented films (BOPET) for flexible packaging, lamination, and electrical insulation.
• Recycled PET (rPET): Serves as feedstock for sustainable manufacturing of fibers, strapping, and new food-contact containers.

Quality Control

Our Polyethylene Terephthalate (PET) is manufactured under strict quality management systems. We provide material tailored to various industry standards, including food-grade (FDA, EU) and fiber-grade specifications. Every batch is tested for key parameters such as intrinsic viscosity (IV), melting point, and color. Certificates of Analysis (COA) documenting purity, physical properties, and compliance are available upon request.

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. Ensure the packaging remains sealed to prevent moisture absorption, which can affect processing characteristics.
