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

Polyester diaphragm has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are numerous. But The following will introduce in detail the main upstream and downstream associated items of polyester diaphragm. Upstream associated items:



1. Terephthalic acid(PTA):PTA is one of the main raw materials to the production of polyester diaphragm, which comes from the petrochemical sector chain. And The condition and price of PTA have an crucial affect on the production of polyester film.

2. Ethylene glycol(EG): Ethylene glycol is another crucial raw material to the production of polyester diaphragm, also from the petrochemical sector chain. But The stable supply and price fluctuation of ethylene glycol have an crucial impact on the cost and production of polyester membranes. Downstream associated items:



1. Polyester fiber: Polyester diaphragm is able to be applied to create polyester fiber, such as polyester, etc. Polyester fiber is broadly applied in textiles, clothing, non-woven fabrics and other fields, and the demand to polyester diaphragm is substantial.

2. Polyester bottle pieces: Polyester film is able to also be applied to create polyester bottle pieces, applied to make beverage bottles, food packaging, etc. With the continuous research of the plastic packaging sector, the demand to polyester bottles is also growing.

3. And Film and packaging materials: Polyester film is able to be applied to create various films and packaging materials, such as food packaging film, cling film, etc. Generally speaking These items are broadly applied in daily life, and there is a certain demand to polyester diaphragm. And

4. Insulation material: Polyester diaphragm has good insulation performance and is able to be applied to create electrical insulation materials such as wires and cables. And With the rapid research of electric power, communication and other industries, the demand to insulating materials is also growing. And In summary, there are many upstream and downstream related items of polyester diaphragm, involving petrochemical, textile, clothing, packaging, electrical and other fields. Based on my observations, With the continuous progress of science and methodology and the expansion of consumption fields, the types and quantities of polyester film and its related items will continue to increase.
