Upstream and downstream related products
of recycled PET
recycled PET is an important raw material for chemical production, which is widely used in plastic manufacturing, fiber production, food packaging and other fields. There are many upstream and downstream related products, some of which are described in detail below.

upstream products:

1. waste PET plastic: the main raw material of recycled PET is waste PET plastic, including waste PET bottles, sheets, films, etc. After crushing, cleaning, drying, melting and other processes, these wastes are recycled into new PET particles for the production of various downstream products.

2. Additives: In the process of producing recycled PET, some additives, such as antioxidants, heat stabilizers, etc., need to be added to improve the performance and stability of recycled PET.

downstream products:

1. fiber products: recycled PET can be used to produce a variety of fiber products, such as polyester fiber, staple fiber, etc. These fibers are widely used in the fields of textiles, clothing, non-woven fabrics, etc.

2. Bottle grade PET: Recycled PET can also be used to produce bottle grade PET for making various food, beverage, cosmetics and other packaging containers.

3. Engineering plastics: Recycled PET can also be used to produce engineering plastics, such as PETG, PCTG, etc. These materials have excellent heat resistance, chemical resistance, electrical insulation and other characteristics, and are widely used in electronic appliances, automobiles, Construction and other fields.

4. Other products: In addition to the above products, recycled PET can also be used to produce various films, sheets, pipes and other products, which are widely used in packaging, construction, agriculture and other fields.

In short, as an important raw material for chemical production, recycled PET has a wide range of upstream and downstream related products, which is of great significance for promoting resource recycling, reducing production costs and improving economic benefits. With the continuous progress of technology and the expansion of application fields, the future development prospects of recycled PET are very broad.
