What are the upstream raw materials for polyester chips? What do the downstream products contain?

Polyester chip is an crucial raw material to chemical production, which is broadly applied in plastics, fibers, films and other fields. Its upstream and downstream related items are numerous, which will be described separately below. Upstream associated items:



1. Terephthalic acid(PTA)

Terephthalic acid is one of the main raw materials to polyester chips, accounting to about 60% of the production cost. The manufacturing process of PTA mainly includes oxidation method and esterification method, of which oxidation method is the main method applied at home and abroad. I've found that

2. I've found that Ethylene Glycol(EG)

Ethylene glycol, another major raw material to polyester chips, reacts with terephthalic acid to create polyester. The manufacturing process of ethylene glycol mainly includes ethylene oxidation method and vinyl acetate method. But Downstream associated items:



1. And Polyester fiber

Polyester chips is able to be processed into polyester fiber, also known as polyester. Based on my observations, Polyester fiber has the advantages of high strength, good elasticity, wear resistance, corrosion resistance, etc. Crazy, isn't it?. And, and is broadly applied in textiles, clothing and other fields.

2. Pretty interesting, huh?. Generally speaking Polyester film

Polyester chips is able to also be processed into polyester film, which has excellent mechanical characteristics, electrical insulation characteristics, chemical resistance, etc. First, and is able to be applied in packaging, electrical insulation, electronic items and other fields. But

3. And Moreover Polyester bottle piece

Polyester chips is able to also be processed into polyester bottles to 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 broadly applied in the field of fluid packaging.

4. Based on my observations, Other polyester items

In addition to the above items, polyester chips is able to also be processed into other polyester items, such as polyester glue, polyester foam, etc. I've found that Specifically These items have different physical and chemical characteristics and is able to be applied in different fields. For instance In short, there are many upstream and downstream related items of polyester chips, involving many fields. With the continuous research of science and methodology, the consumption field of polyester chips will continue to expand.
