In the field of chemical production raw materials, SIS (styrene-isoprene-styrene) terpolymer, as an important elastomer material, has excellent weather resistance, aging resistance, tear resistance and processability, and is widely used in many fields. The upstream and downstream related products of SIS mainly include the following aspects:

upstream related products:

1. Styrene: Styrene is an important monomer raw material of SIS, mainly produced by alkylation reaction of ethylene and benzene. The market price fluctuation of styrene has a great influence on the production cost and price of SIS.
2. Isoprene: Isoprene is another important monomer raw material for SIS, which is mainly separated from the five fractions of petroleum cracking carbon. The supply stability and price level of isoprene have an important influence on the production of SIS.

downstream related products:

1. Thermoplastic elastomer: SIS can be used as a base material, blended or copolymerized with other polymers to produce various thermoplastic elastomers (TPE). These TPE products have excellent processing performance and mechanical properties, and are widely used in automobiles, home appliances, construction, packaging and other fields.
2. Adhesive: SIS has good adhesion and can be used to make various adhesives, such as pressure-sensitive adhesives, hot melt adhesives, etc. These adhesives are widely used in packaging, footwear, construction, automotive and other fields.
3. Modifier: SIS can be used as a modifier to improve the performance of other polymer materials. For example, adding SIS to plastics can improve the toughness, impact resistance and processability of plastics.
4. Waterproof material: SIS has good weather resistance and aging resistance, and can be used to make waterproof materials, such as waterproof coiled materials, waterproof coatings, etc.

In short, SIS's upstream and downstream related products cover many fields, with a wide range of applications and huge market potential. With the continuous development of science and technology, the types and performance of SIS and its related products will be further improved, providing more possibilities for the development of various fields.
