In the field of chemical production raw materials, the upstream and downstream related products of other plasticizers are quite abundant. This article will introduce these related products in detail, including their production processes, application areas, and market trends.

1. upstream related products

1. Phthalic anhydride
phthalic anhydride is one of the important raw materials for other plasticizers, mainly used in the production of phthalate plasticizers. The production process of phthalic anhydride mainly includes oxidation method and catalytic method, of which oxidation method is more commonly used. Phthalic anhydride has a wide range of applications. In addition to the production of plasticizers, it can also be used to produce unsaturated polyester resins, pesticides, and pharmaceutical intermediates.
2. caprylic/capric acid
caprylic/capric acid is also an important raw material for other plasticizers, mainly used in the production of terephthalate plasticizers. These fatty acids can be obtained by hydrogenation of oils and fats followed by fractionation, or by direct cracking from petroleum. The application fields of caprylic/capric acid include plastics, rubber, grease, fragrance, etc.

2. downstream related products

1. Polyvinyl chloride (PVC)
Polyvinyl chloride is one of the main application areas of plasticizers. Plasticizers can be added to PVC to improve its flexibility, processability and low-temperature impact resistance. PVC is widely used in building materials, wire and cable, packaging materials, medical equipment and other fields.
2. Rubber products
plasticizers can also be added to rubber products to improve their processing and use properties. Rubber products are widely used in automotive, aviation, construction, home appliances and other fields.
3. Coating
plasticizer can also be added to the coating to improve the flexibility and weather resistance of the coating. Coatings are widely used in construction, automobiles, ships, furniture and other fields.

3. market trends

With the increase in environmental awareness and consumer health and safety concerns, the demand for traditional plasticizers is gradually decreasing. Therefore, the development of environmentally friendly and safe new plasticizers has become a market trend. Bio-based plasticizers, citric acid ester plasticizers and other environmentally friendly plasticizers are gradually favored by the market.

4. recommendations and outlook

for other plasticizer upstream and downstream related products, it is recommended that enterprises strengthen technological research and development and innovation, improve product quality and performance to meet market demand. At the same time, pay attention to environmental protection and sustainable development, promote green production processes and products, and improve the competitiveness of enterprises. Looking to the future, with the progress of science and technology and the strengthening of environmental protection policies, other plasticizers and their related products will play a greater role in the field of chemical production raw materials.

In short, the upstream and downstream related products of other plasticizers include raw materials such as phthalic anhydride, caprylic/capric acid, as well as applications in polyvinyl chloride, rubber products, coatings and other fields. With the change of market demand and the strengthening of environmental protection policies, enterprises need to strengthen technological innovation and product upgrading to improve competitiveness and adapt to market changes.
