The nature and use
of semi-extinction POY in the field of raw materials for chemical production
1. Introduction

In the field of raw materials for chemical production, semi-extinction POY is an important polymer material and is widely used in many fields. This article will detail the nature and use of semi-extinction POY so that readers can have a deeper understanding of it.

2. the properties of semi-extinction POY

semi-extinction POY (partially oriented yarn) is a kind of polyester fiber with special properties. The chain segment in its molecular structure has a certain degree of orientation, but it does not reach complete orientation. This special structure gives the following properties to the semi-extinction POY:

1. High strength: Due to the orientation of the molecular chain segments, the semi-extinction POY has higher strength and can withstand greater tension.
2. Thermal stability: Semi-extinction POY has good thermal stability and can be used at higher temperatures without significant changes in performance.
3. Chemical resistance: Semi-extinction POY has good corrosion resistance to many chemical reagents and can be used in harsh chemical environments.

3. the use of semi-extinction POY

semi-extinction POY in the chemical production of raw materials in the field of a wide range of uses, the following list of several main aspects:

1. Textile manufacturing: semi-extinction POY can be used as textile manufacturing raw materials, used in the production of clothing, home textile products. Its better strength and thermal stability make the textile have better durability and comfort.
2. Industrial filter cloth: semi-extinction POY can be used as raw material of industrial filter cloth for manufacturing filter equipment. Its chemical resistance and thermal stability enable the filter cloth to be used in harsh chemical environments and have a long service life.
3. Composite material reinforcement: semi-extinction POY can be used as a reinforcement of composite materials to improve the strength and toughness of composite materials. For example, it can be combined with a matrix material such as resin to produce a high-strength structural member.

4. conclusion

semi-extinction POY as an important polymer material, has a wide range of applications in the field of chemical production raw materials. Its unique properties and structure make it play an important role in textile manufacturing, industrial filter cloth and composite reinforcement. With the continuous development of science and technology, the application field of semi-extinction POY will continue to expand, and make greater contributions to the development of chemical production raw materials.
