Product overview
Styrene Monomer, also known as Vinylbenzene, Ethenylbenzene, or Phenylethylene, with the molecular formula C₈H₈ and CAS number 100-42-5, is a clear, colorless to pale yellow liquid with a characteristic sweet odor . As one of the most important industrial monomers globally, styrene is produced primarily through the catalytic dehydrogenation of ethylbenzene . With a boiling point of 145°C and a flash point of 31°C, it is classified as a flammable liquid . Due to its high reactivity and tendency to polymerize, commercial styrene is typically stabilized with Tert-Butyl Catechol (TBC) to prevent premature polymerization during storage and transport . As the essential building block for polystyrene (PS), expanded polystyrene (EPS), acrylonitrile-butadiene-styrene (ABS), styrene-butadiene rubber (SBR), and unsaturated polyester resin (UPR), styrene is indispensable across packaging, construction, automotive, electronics, and consumer goods industries .

| Appearance | Clear, colorless to pale yellow liquid | Indicates product quality; dark color may suggest degradation or premature polymerization . |
| Water Content | ≤0.03% (300 ppm) | Critical for polymerization processes; excess water can act as a chain transfer agent and affect reaction rates . |
| TBC Content | 10-15 ppm (minimum 10 ppm) | Stabilized styrene requires TBC to prevent premature polymerization during storage and transport . |
| Polymer Content | ≤10 ppm | Low polymer content ensures consistent processing and prevents equipment fouling . |
| Boiling Point | 145°C | Determines distillation and recovery conditions; influences reactor design and process safety . |
| Flash Point | 31°C (Closed Cup) | Flammable; dictates handling, storage, and transportation protocols . |
| Density | ~0.906 g/mL at 20°C | Affects volumetric calculations for reactor charging and shipping . |
| Vapor Pressure | 6 mmHg at 25°C | Moderate vapor pressure requires adequate ventilation during use . |

Polystyrene (PS) and Expanded Polystyrene (EPS): The Largest Markets
The largest demand for styrene monomer comes from the production of polystyrene and expanded polystyrene:
Polystyrene (PS) Production:
Process: Free radical polymerization of styrene monomer
Types: General-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS)
Applications: Disposable cups, food containers, CD cases, appliance housings
Expanded Polystyrene (EPS) Production:
Process: Suspension polymerization of styrene with blowing agents
Applications: Protective packaging, insulation boards, lightweight concrete forms
Benefits: Excellent thermal insulation, shock absorption, and lightweight properties
Quality Requirements for PS/EPS:
High purity styrene monomer with low impurities
Consistent TBC levels for controlled polymerization initiation
Low polymer content to prevent defects in final products
ABS Resin: Engineering Thermoplastics from Styrene
Styrene for ABS resin is critical for producing one of the most widely used engineering thermoplastics:
ABS Copolymer Production:
ABS is a terpolymer of three monomers:
