Application of sling polyester
Polyester terephthalate (PET) is a high molecular compound. Polyethylene terephthalate (PET) is produced by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). Part of the PET is finally produced by underwater pelleting. Fiber-grade polyester chips are used to make polyester staple fibers and polyester filaments. They are the raw materials for polyester fiber companies to process fibers and related products. As the largest output of chemical fiber, polyester fibers account for nearly 80% of the market share of the chemical fiber industry. The market changes and development trend of the polyester series are the focus of the chemical fiber industry. At the same time, PET is also used for bottles, films, etc., and is widely used in the packaging industry, electronic appliances, medical and health, construction, automotive and other fields, among which packaging is the largest non-fiber application market for PET, and it is also the fastest growing field for PET. . It can be said that polyester chips are an important intermediate product that connects petrochemical products and products of various industries.
