SEBS (styrene-ethylene-butadiene-styrene) is an important thermoplastic elastomer, which is widely used in the field of chemical production raw materials. The upstream and downstream related products of SEBS mainly include the following aspects:

upstream products:

1. Styrene: Styrene is one of the main raw materials of SEBS, which is used for copolymerization with ethylene and butadiene.
2. Ethylene: Ethylene is another main raw material in SEBS, which participates in the copolymerization reaction together with styrene and butadiene.
3. Butadiene: Butadiene is the third raw material in SEBS, which is copolymerized with styrene and ethylene to form SEBS elastomers.

downstream products:

1. Modified plastics: SEBS can be added to plastics as a modifier to improve its toughness, impact resistance and processing performance, and is widely used in home appliances, automobiles, building materials and other fields.
2. Thermoplastic elastomer: SEBS itself is a kind of thermoplastic elastomer, which can be blended or copolymerized with other polymers to prepare various thermoplastic elastomer materials with excellent performance, which are used in the manufacture of shoe materials, seals, wires and cables, etc.
3. Adhesive: SEBS can be used as the basic component of adhesives to prepare various adhesives, such as hot melt adhesives, pressure sensitive adhesives, etc.
4. Coating: SEBS can be added to the coating to improve the toughness, weather resistance and crack resistance of the coating.

In short, as an important chemical raw material, SEBS has a wide range of upstream and downstream related products, involving many fields, such as plastic modification, thermoplastic elastomer preparation, adhesives and coatings.
