Polyester chip is an important raw material for chemical production, which is widely used in plastics, fibers, films and other fields. Its upstream and downstream related products are numerous, which will be described separately below.
upstream related products:
1. Terephthalic acid (PTA)
Terephthalic acid is one of the main raw materials for polyester chips, accounting for about 60% of the production cost. The production process of PTA mainly includes oxidation method and esterification method, of which oxidation method is the main method used at home and abroad.
2. Ethylene glycol (EG)
Ethylene glycol is another main raw material for polyester chips, which reacts with terephthalic acid to produce polyester. The production process of ethylene glycol mainly includes ethylene oxidation method and vinyl acetate method.
downstream related products:
1. Polyester fiber
polyester chips can be processed into polyester fiber, also known as polyester. Polyester fiber has the advantages of high strength, good elasticity, wear resistance, corrosion resistance, etc., and is widely used in textiles, clothing and other fields.
2. Polyester film
Polyester chips can also be processed into polyester film, which has excellent mechanical properties, electrical insulation properties, chemical resistance, etc., and can be used in packaging, electrical insulation, electronic products and other fields.
3. polyester bottle
polyester chips can also be processed into polyester bottle, used in the production of beverage bottles, food packaging bottles and so on. Polyester bottles have the advantages of light weight, high strength and good transparency, and are widely used in the field of liquid packaging.
4. Other polyester products
In addition to the above products, polyester chips can also be processed into other polyester products, such as polyester glue, polyester foam, etc. These products have different physical and chemical properties and can be applied in different fields.
In short, there are many upstream and downstream related products of polyester chips, involving many fields. With the continuous development of science and technology, the application field of polyester chips will continue to expand.
