Product Description
Our Polyethylene Terephthalate (PET) Resin, also known as Polyester resin, is a high-performance semi-crystalline thermoplastic widely used in packaging and textile industries. Manufactured through polycondensation of ethylene glycol and terephthalic acid, it offers outstanding clarity, strength-to-weight ratio, and chemical resistance.
Key Advantages:
Common applications include PET bottles for water, carbonated drinks, juices, edible oils, food containers, polyester staple fiber, filament yarn, films, and sheets. We supply various Intrinsic Viscosity (IV) grades (0.70–0.85 dl/g typical for bottles) to meet your exact processing needs. Consistent quality, low acetaldehyde content, and fast delivery guaranteed.
Applications: Beverage & Food Packaging, Textiles (clothing, technical fabrics), Films & Sheets, Strapping, Industrial Uses.
