Styrene

Styrene is a crucial liquid organic chemical monomer with the formula C₆H₅CH=CH₂. It is a colorless to yellowish, transparent, oily liquid with a distinct, unpleasant sweet odor (pungent at high concentrations). The vinyl group in its molecule makes it highly susceptible to polymerization, rendering it an indispensable core raw material for producing synthetic materials such as Polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS), Styrene-Acrylonitrile copolymer (SAN), and Styrene-Butadiene Rubber (SBR). Due to its tendency to polymerize and volatilize, it typically requires the addition of an inhibitor (e.g., TBC) and storage under cool conditions during transport and storage.

Product Parameters


Product Name (English)Styrene
CAS No.100-42-2
DescriptionAn important organic compound used as a building block for many plastics. It is a colorless, oily liquid that readily polymerizes. The main use of styrene is in the production of polystyrene, expanded polystyrene (EPS), and various copolymers, which are used to make consumer goods, insulation, and packaging.
SpecificationsPurity > 99.9%.
Packaging180 KG/drum.

Basic Properties

  • Molecular Formula： C₈H₈

  • Appearance： Colorless to yellow liquid, sweet odor

  • Density (20°C)： 0.906 g/cm³

  • Boiling Point： 145°C

  • Melting Point： -30.6°C

  • Flash Point： 31°C (Flammable)

  • Explosive Limits： 0.9–6.8% vol (in air)

  • Self-Poly. ：Temp. >50°C (requires TBC inhibitor)

  • Carcinogenicity： IARC Group 2B (Possible carcinogen)

Main Applications


  1. Polymer Production (>90%):

    • Polystyrene (PS) → Food packaging/electronics housings

    • ABS Resins → Automotive parts/consumer electronics

    • SBR Rubber → Tires/shoe soles

  2. Chemical Intermediate:

    • Unsaturated Polyester Resins (UPR) (fiberglass composites)

    • Styrene-Butadiene Latex (SBL) (paper coating)

  3. Others:

    • Modifier for ion-exchange resins

    • Analytical standard

Safety Precautions


  • Health Hazards:

    • Inhalation causes mucous membrane irritation, headache, neurasthenia (TLV-TWA: 20 ppm)

    • Chronic exposure linked to leukemia risk (IARC 2B)

    • Liquid causes skin burns/allergy (high permeability)

  • Physical Hazards:

    • Runaway polymerization → vessel rupture (TBC ≥10 ppm required)

    • Static ignition hazard (conductivity <1 pS/m)

  • Protection:

    • Temperature Control:
      → Storage <25°C (cooling system in summer)
      → NEVER steam-heat (>50°C triggers explosion)

    • Inhibitor Monitoring:
      → Weekly TBC testing (HPLC)
      → Maintain O₂ >0.1% to suppress polymerization

    • PPE:
      → Supplied-air respirator (Level A) (mandatory)
      → Viton gloves + face shield

  • Emergency:

    • Thermal runaway: Inject DNBP inhibitor + nitrogen blanketing

    • Spill: Absorb with vermiculite; NO compressed air!
