Application range of polyester products

Polyester Polyethylene terephthalate (PET) is a polymer compound. Polyethylene terephthalate (PET) is produced by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG), and part of the PET is generated by underwater granulation. Fiber-grade polyester chips are used to manufacture polyester staple fibers and polyester filaments. They are the raw materials for polyester fiber companies to process fibers and related products. Polyester occupies nearly 80% of the market share in the chemical fiber industry. Therefore, the market changes and development trends of polyester series are the focus of the chemical fiber industry. At the same time, polyester also has bottles, films and other uses, which are widely used in the packaging industry, electronic appliances, medical and health care, construction, automobiles and other fields. Among them, packaging is a non-fiber app store occupied by polyester, and it is also an area where PET grows rapidly. It can be said that polyester chips are an important intermediate product connecting petrochemical products and products in multiple industries.
