About Styrene Monomer

Styrene Monomer is a clear, colorless to slightly yellow liquid with a sweet, aromatic odor. It is a highly reactive vinyl compound that polymerizes easily and is mainly used as a building block for synthetic polymers. With its combination of rigidity and processability, styrene is a core raw material in lightweight, durable, and cost-effective plastic production.

Applications / Uses

Styrene is a key monomer in the production of various plastics and resins:

  • Plastics: Polymerized to form polystyrene, used in packaging, disposable containers, insulation, and consumer goods.
  • Rubber Industry: Used in the production of styrene-butadiene rubber (SBR) for tires and mechanical rubber goods.
  • Resins: Essential in ABS and SAN resins, widely used in automotive parts, electronics, and appliances.
  • Construction: Found in insulation materials, coatings, and reinforced plastics for panels and piping.
  • Paints & Coatings: Used in alkyd and polyester resins to enhance gloss, durability, and drying speed.
  • Marine & Automotive: Utilized in fiber-reinforced composites for boats, vehicles, and structural parts.

Storage & Handling

  • Store in a cool, dry, well-ventilated place in inhibitor-stabilized containers.
  • Keep away from heat, light, and ignition sources — styrene is flammable and prone to polymerization.
  • Use chemical-resistant gloves, safety goggles, and protective clothing during handling.
  • Ensure proper ventilation or respiratory protection to avoid exposure to vapors.
