Applications of 100-42-5
Styrene has a wide range of applications due to its versatile chemical properties:
- Polystyrene Production: Approximately two-thirds of all styrene produced is used for making polystyrene, which is used in packaging materials, insulation products, and disposable cutlery.
- Synthetic Rubber: Styrene is a key component in the production of acrylonitrile-butadiene-styrene rubber and styrene-butadiene rubber.
- Coatings and Adhesives: Styrenic polymers are used in various coatings and adhesives due to their strong adhesive properties.
- Composite Materials: Styrene-based resins are utilized in the manufacturing of composite materials for automotive and aerospace applications.
