SBS (styrene-butadiene-styrene) is an important raw material for chemical production, which is widely used in plastic modification, road construction, shoe materials, adhesives and other fields. In the upstream and downstream related products of SBS, the upstream raw materials mainly include styrene, butadiene and other monomers, while the downstream products involve a variety of plastic modifiers and functional materials.

1. Upstream Raw Material

1. Styrene
Styrene is one of the main raw materials for SBS and is used to copolymerize with butadiene to produce SBS. The market price fluctuation of styrene has an important influence on the production cost of SBS.
2. Butadiene
Butadiene is another important raw material in SBS, which is copolymerized with styrene to form SBS. The main sources of butadiene are naphtha cracking and ethylene oxidative dehydrogenation.

2. downstream product

1. Plastic modifier
SBS can be used as a plastic modifier to improve the toughness, impact resistance and processing performance of plastics. SBS can be applied to a variety of plastic products, such as pipes, plates, sheets, etc.
2. Road construction material
SBS can be modified asphalt to improve the weather resistance, crack resistance and high temperature stability of asphalt, which is widely used in the field of road construction.
3. shoe material
SBS can be used as the raw material of shoe material to improve the wear resistance, slip resistance and comfort of the sole.
4. Adhesive
SBS can be used as a raw material of an adhesive to improve the adhesive strength, water resistance, heat resistance, etc.

In short, the upstream and downstream related products of SBS involve many fields and play an important role in promoting the development of the chemical industry. At the same time, with the continuous progress and application of science and technology, SBS upstream and downstream products are also expanding and extending, injecting new vitality into the development of the chemical industry.
