Plastic additives are an important part of the field of chemical production raw materials, which are used to improve the performance and processing of plastics. This article will explore the upstream and downstream related products of plastic additives, including upstream raw materials, production processes and downstream applications.

1. upstream raw material

1. basic chemical raw materials: the production of plastic additives can not be separated from basic chemical raw materials, such as petrochemical raw materials, alcohol, acid, alkali and so on. These raw materials are converted into various components of plastic additives through chemical reaction and processing.
2. Functional additives: In addition to basic chemical raw materials, the production of plastic additives also requires functional additives, such as catalysts, antioxidants, light stabilizers, etc. These additives make it possible to adjust and optimize the properties of plastic auxiliaries.

2. production process

plastic additives production process mainly includes mixing, reaction, granulation, drying and other steps. The production process requires strict control of parameters such as temperature and pressure to ensure product quality and stability. At the same time, the waste and by-products produced in the production process also need to be environmentally friendly.

3. Downstream Application

Plastic additives are widely used in the production of various plastic products, such as the following related products:

1. Plastic packaging materials: Plastic additives can improve the weather resistance, oxidation resistance, Anti-ultraviolet and other properties, extend the service life of packaging materials.
2. Building materials: Plastic additives can improve the processing performance of building materials, improve their mechanical properties, heat resistance, cold resistance, etc.
3. Household appliances: Plastic additives can be used to manufacture the shells and parts of household appliances to improve the appearance quality and durability of products.
4. Automotive industry: Plastic additives can be used to manufacture interior and exterior parts of automobiles to improve the aging resistance, flame retardancy, and lightweight of materials.

In short, the upstream and downstream related products of plastic additives cover a wide range of fields from basic chemical raw materials to various plastic products. With the continuous progress of science and technology and the continuous improvement of application demand, the production technology and product types of plastic additives are also developing.
