Polyester is a high molecular weight compound. Is produced by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG) to produce polyethylene terephthalate (PET), in which part of the PET is finally formed by underwater pelletization. Fiber grade polyester chips used in the manufacture of polyester staple fiber and polyester filament, is the supply of polyester fiber processing fiber and related products, raw materials. Polyester fiber as the largest production in the varieties, accounting for nearly 80% of the chemical fiber industry market share, the polyester series of market changes and trends in the chemical fiber industry is the focus of attention. At the same time there are bottles of polyester, film and other uses, are widely used in packaging, electronic appliances, health, construction, automotive and other fields. The packaging is the largest non-fiber polyester application market, but also the fastest growing areas of PET. Polyester chips can be said to connect petrochemical products and a number of industry products, an important intermediate product.
