Styrene Monomer (SM) CAS 100-42-5
Sinochem is a major Styrene supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Styrene.
Styrene Monomer (SM), also known as Vinylbenzene or Ethenylbenzene, is a vital organic compound with the molecular formula C8H8. As a colorless, oily liquid with a characteristic aromatic odor, it serves as a fundamental building block in the global polymer industry. Our Styrene is produced with high purity to ensure excellent polymerization reactivity for high-end manufacturing.
- Excellent Polymerization Reactivity: Readily polymerizes via various methods to form diverse materials.
- Good Mechanical Properties: Polymers derived from styrene exhibit rigidity, hardness, and dimensional stability.
- Chemical Resistance: Offers good resistance to many acids, bases, and salts.
Styrene Description

Flashing point: 31.1±0.0 °C
Appearance: Colorless transparent oily liquid
Solubility: Insoluble in water, soluble in ethanol, ether and other organic solvents.
Properties: Colorless oily liquid with aromatic odor, slightly soluble in water, but soluble in ethanol, ether, methanol, acetone and carbon disulfide. Easy to polymerize, release heat during polymerization, and easily cause explosion.
Package: Supplied in galvanized iron drums (180kg/drum), IBC tanks, or ISO tanks.
Storage:
1. Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. The package should be sealed to avoid contact with air. It should be stored separately from oxidants and acids, and never mixed. It should not be stored in large quantities or for a long time. Use explosion-proof lighting and ventilation facilities. Mechanical equipment and tools that are prone to sparks should not be used. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
2. Use galvanized iron barrels for packaging, add inhibitors during packaging, and store at low temperature (below 25℃) or in a refrigerated warehouse to prevent polymerization and deterioration. Keep away from fire sources and avoid direct sunlight. The storage period is one month. Store and transport as flammable and toxic items.
Shelf Life: Recommended use within 1 month to ensure optimal monomer quality.
Safety protection: This product is toxic, less toxic than benzene, but it will irritate the skin and respiratory tract at high concentrations.
About Us: With over many years as a certified Styrene manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Styrol Applications
Styrene is indispensable in the production of a wide range of plastics and synthetic resins:
- Polystyrene (PS): Used for food packaging, disposable cutlery, and laboratory ware.
- ABS & SAN Resins: Essential for automotive parts, electronic housings, and household appliances due to their impact resistance.
- Synthetic Rubber (SBR): A primary component in tire manufacturing and technical rubber goods.
- Unsaturated Polyester Resins (UPR): Widely used in fiberglass reinforcement (FRP) for boat hulls and construction panels.
- Specialty Chemicals: Acting as an intermediate for fragrances and pharmaceutical synthesis (e.g., cinnamyl chloride).
As a dedicated chemical exporter, we provide:
- Strict Quality Control: Every batch is tested for purity and polymer content before loading.
- Hazardous Goods Handling: Full compliance with UN 2055 shipping regulations.
- Competitive Pricing: Direct factory sourcing to help you reduce procurement costs for bulk orders.
