Polyester chip is an important raw material for chemical production, which is widely used in plastics, fibers, films, packaging and other fields. This article will detail the properties and uses of polyester chips.

1. the nature of polyester chip

polyester chip is a kind of polymer compound, by dibasic acid and diol by polycondensation reaction. Its molecular structure contains ester groups, so it has good chemical resistance, heat resistance, weather resistance, electrical insulation and other properties. In addition, polyester chips also have the following properties:

1. High mechanical strength: Polyester chips have high mechanical strength and can be used to make products that need to withstand a certain amount of tension and pressure.

2. Light weight: The density of polyester chips is small, so the products made are light in weight and easy to handle and use.

3. Good processing performance: Polyester chips have good processing performance and can be processed into products of various shapes through injection molding, extrusion, blow molding and other processes. The use of

2. polyester chips

polyester chips are widely used in various fields. The following are its main uses:

1. Fiber field: Polyester chips are the main raw material for the manufacture of polyester fibers. Polyester fibers have high strength and elasticity. Good, wear-resistant, easy to clean and other characteristics, widely used in clothing, home textiles, industrial textiles and other fields.

2. Plastic field: Polyester chips can be used to manufacture various plastic products, such as beverage bottles, food packaging containers, home appliance shells, etc.

3. Film field: Polyester chips can be used to make various films, such as packaging films, insulating films, magnetic films, etc.

4. Other fields: Polyester chips can also be used to make coatings, adhesives, insulating materials, etc.

3. the development trend of polyester chips

With the continuous development of science and technology, the application field of polyester chips is also expanding. In the future, polyester chips will develop in the direction of high performance, high functionality and environmental protection. For example, the development of antibacterial, anti-ultraviolet and other functions of polyester chips to meet people's health, environmental protection and other needs.

4. conclusion

In conclusion, as an important raw material for chemical production, polyester chips have a wide range of applications and good prospects for development. In the future, with the continuous development of science and technology, the application field of polyester chips will continue to expand, bringing more convenience and safety to people's lives.
