The main chemical component of bottle grade chips is polyethylene terephthalate (PET).
1、 What is bottle grade polyester chip?
Bottle grade polyester chips are one of the polyester materials widely used in fields such as bottles and packaging. During its manufacturing process, PET needs to be melted at high temperatures and pulled into slices. The thickness of the slices is generally between 0.1-0.5 millimeters, and their shape is long and thin filaments.
2、 What is the chemical composition of bottle grade polyester chips?
The main chemical component of bottle grade polyester chips is polyethylene terephthalate (PET). PET is a polymer compound, chemically known as polyester thermoplastic resin, and is a common synthetic fiber and plastic raw material. PET has excellent physical properties such as high hardness, good corrosion resistance, and high transparency, making it widely used in various fields. In addition to PET, bottle grade polyester chips also contain small amounts of copolymers and additives.
3、 What are the application areas of bottle grade polyester chips?
Bottle grade polyester chips are widely used in fields such as bottles and packaging. In the field of bottles, PET slices are mainly used in the manufacturing of beverage bottles, pharmaceutical bottles, etc; In the field of packaging, PET slices are mainly used to make various food packaging, pharmaceutical packaging, chemical packaging, etc.
4、 How to solve the environmental problems of bottle grade polyester chips?
The extensive use of bottle grade polyester chips can also bring environmental issues. But there are already many solutions available. For example, bottle grade polyester chips can be recycled and reused, and bottles made from PET chips can be recycled and reused multiple times; Meanwhile, a large amount of PET waste can also be recycled and reused to produce other PET products, reducing resource waste.
【 Conclusion 】
The chemical composition of bottle grade polyester chips is polyethylene terephthalate (PET), which has excellent physical properties and is widely used in fields such as bottles and packaging. We also need to pay attention to its environmental issues, actively take measures for recycling and reuse, and reduce resource waste.
