ABS/AS polymer is an important raw material widely used in the field of chemical production. It has excellent physical properties, chemical stability and processing performance, so it is widely used in automotive, electronics, construction, home appliances and other fields. In the production process of ABS/AS polymer, upstream and downstream related products play a vital role. This article will detail the upstream and downstream associated products of ABS/AS polymers.

1. Upstream Related Products

1. Styrene
Styrene is one of the main raw materials for ABS/AS polymers, accounting for a large proportion of the total raw materials. Styrene is a colorless and transparent oily liquid with aromatic odor. It is mainly produced by the reaction of ethylene and benzene at high temperature and high pressure. The price fluctuation of styrene has a great influence on the cost of ABS/AS polymer.

2. Acrylonitrile
Acrylonitrile is another main raw material of ABS/AS polymer, which accounts for a large proportion of the total raw material. Acrylonitrile is a colorless transparent liquid with a pungent odor. It is mainly produced by the reaction of propylene and ammonia at high temperature and high pressure. The purity of acrylonitrile has a great influence on the properties of ABS/AS polymer.

3. Butadiene
Butadiene is the third raw material of ABS/AS polymer, which accounts for a small proportion of the total raw material. Butadiene is a colorless gas with a pungent odor. It is mainly produced by naphtha cracking. The content of butadiene has a great influence on the elasticity and toughness of ABS/AS polymer.

2. downstream related products

1. Auto parts
ABS/AS polymer has excellent impact resistance, heat resistance, weather resistance and processing performance, so it is widely used in the manufacture of auto parts, such as dashboard, steering wheel, door panel, etc.

2.
of household appliances ABS/AS polymers can also be used in the manufacture of household appliances, such as the housings and internal parts of washing machines, refrigerators, air conditioners, etc.

3.
of electronic products ABS/AS polymer has excellent insulation properties and processing properties, so it is widely used in the manufacture of electronic products, such as mobile phones, TVs, computers and other housing and internal parts.

4. Building materials
ABS/AS polymers can also be used in the manufacture of building materials, such as pipes, plates, doors and windows, etc. It has good weather resistance, heat resistance and processing performance, and can meet the requirements of different environmental conditions.

In summary, the upstream and downstream related products of ABS/AS polymers are very extensive and involve many fields. The price and purity of upstream raw materials have a greater impact on the cost and performance of ABS/AS polymers, so the quality and procurement costs of raw materials need to be strictly controlled. The application fields of downstream products continue to expand, and the performance and quality requirements of ABS/AS polymers are also increasing. Therefore, it is necessary to continuously optimize the production process and improve product quality to meet market demand.
