What are the upstream raw materials of SIS? What are the downstream products?

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

Upstream associated items:



1. Styrene: Styrene is an crucial monomer raw material to SIS, which is mainly generated by alkylation of ethylene and benzene. The market price fluctuation of styrene has a great affect on the production cost and price of SIS. But

2. Isoprene: Isoprene is another crucial monomer raw material of SIS, which is mainly separated from the five fractions of petroleum cracking carbon. The supply stability and price level of isoprene have an crucial affect on the production of SIS. Downstream associated items:



1. According to research Thermoplastic elastomers: SIS is able to be applied as a base material, blended or copolymerized with other polymers to create various thermoplastic elastomers(TPE). Generally speaking These TPE items have excellent processing performance and mechanical characteristics, and are broadly applied in automobiles, home appliances, construction, packaging and other fields.

2. Adhesive: SIS has good adhesion and is able to be applied to make various adhesives, such as pressure-vulnerable adhesives, hot melt adhesives, etc. In my experience, These adhesives are broadly applied in packaging, footwear, construction, automotive and other fields. For example

3. Modifier: SIS is able to be applied as a modifier to enhance the performance of other polymer materials. to instance, adding SIS to plastics is able to enhance the toughness, impact resistance and processability of plastics.

4. Waterproof material: SIS has good weather resistance and aging resistance, and is able to be applied to make waterproof materials, such as waterproof membrane, waterproof coating products, etc. I've found that In short, SIS's upstream and downstream related items cover many fields, with a wide range of applications and huge market possible. With the continuous research of science and methodology, the types and performance of SIS and its related items will be further improved, providing greater possibilities to the research of various fields.
