The nature and use
of aromatic plasticizer in the field of chemical production raw materials
1. Introduction

aromatic plasticizer is an important additive widely used in plastic processing industry, which plays a significant role in improving the performance of plastic products and improving processing efficiency. This article will detail the properties and uses of aromatic plasticizers so that readers can have a deeper understanding of them.

2. the properties of aromatic hydrocarbon plasticizers

1. Chemical stability: aromatic hydrocarbon plasticizers have good chemical stability and are not easy to chemically react with other components in plastics, thereby ensuring the long-term stability and durability of plastic products.
2. Low volatility: Aromatic plasticizers have low volatility, which can reduce the volatile loss of plastic products during processing and use, and improve product quality and life.
3. Good compatibility: Aromatic plasticizers have good compatibility with a variety of plastic matrices, can be evenly dispersed in plastics, reduce the glass transition temperature of plastics, and improve the flexibility of plastics.

3. The use of aromatic hydrocarbon plasticizers

1. Improve the flexibility of plastics: The main function of aromatic hydrocarbon plasticizers is to improve the flexibility of plastics, reduce their hardness, and make plastic products more elastic and ductile. This feature makes aromatic plasticizers widely used in hoses, films, cables and other plastic products that require a certain degree of flexibility.
2. Improve the processing performance of plastics: The addition of aromatic plasticizers can reduce the melt viscosity of plastics and improve their fluidity, thereby improving the processing performance and production efficiency of plastics. This feature makes aromatic plasticizers widely used in plastic processing such as injection molding and extrusion.
3. Improve the cold resistance of plastics: The addition of aromatic plasticizers can reduce the glass transition temperature of plastics and improve their cold resistance, so that plastic products can be used normally in low temperature environments. This characteristic makes aromatic plasticizers have important application value in the preparation of cold-resistant plastic products.

4. Application Examples of Aromatic Plasticizers

1. PVC Hose: In the production process of PVC hose, by adding aromatic plasticizers, the hardness of PVC can be reduced, its flexibility can be improved, and the hose has better bending performance and folding resistance.
2. cable material: in the production of cable material, the addition of aromatic hydrocarbon plasticizer can improve the flexibility of the cable material, reduce its hardness, so that the cable has better bending resistance and low temperature environment performance.
3. Seals: In the production of seals, the addition of aromatic plasticizers can improve the elasticity and sealing performance of sealing materials, and increase their service life and reliability.

5. conclusion

aromatic plasticizer as an important plastic additive, by improving the properties and processing performance of plastics, provides a strong support for the wide application of plastic products. In the future development, with the continuous improvement of scientific and technological progress and environmental protection requirements, aromatic plasticizers will continue to play an important role and contribute to the development of the plastics processing industry.
