Products Description
What is Styrene CAS 100-42-5?
Styrene is a colourless oily liquid with an aromatic odour, which is slightly soluble in water and soluble in ethanol, ether, methanol, acetone and carbon disulphide. Styrene monomer also known as vinyl benzene, that serves as a crucial building block in the chemical industry. It's a synthetic chemical derived from petroleum or natural gas by-products and is used to produce various plastics, synthetic rubbers, and resins.


Applications:
For Plastic production: Styrene monomer (SM) is a major raw material for the plastics industry and is used to produce a variety of styrene-based polymers and copolymers. SM is polymerized to form polystyrene (PS), which is used in disposable tableware, packaging materials, and electronics housings, and it is copolymerized with other monomers, such as acrylonitrile and butadiene, to produce materials such as ABS and SBR (Styrene Butadiene Rubber) materials.

Other Applications:
- Unsaturated polyester resin: Styrene monomer is used as a crosslinking agent in the production of unsaturated polyester resin.
- Coatings and adhesives: In the coating industry, It can be involved in the synthesis of alkyd resins, acrylic resins and other coating resins, which can improve the performance of coatings; in the field of adhesives, styrene material can be used in the preparation of high-performance adhesives.
