1.Product Property
Styrene is a colorless to yellowish, oily liquid with a characteristic sweet yet penetrating odor. It is less dense than water, practically insoluble in water, but miscible with most organic solvents. It is highly flammable and readily polymerizes on exposure to light, heat or oxygen unless properly inhibited .
2.Technical Norm
| Parameter | Specification |
| Appearance | Colorless liquid |
| Purity (GC) | ≥ 99.9 % |
| Water content | ≤ 0.02 % |
| Aldehydes (as benz.) | ≤ 0.01 % |
| Inhibitor (TBC) | 10–15 ppm |
| Color (APHA) | ≤ 10 |
3.Application Scope and Usage
Styrene is the essential monomer for polystyrene and a wide range of copolymers such as ABS, SBR and SBS. These materials are processed into packaging foams, food containers, household goods, automotive parts, and construction panels. It is also used as a reactive solvent in unsaturated polyester resins for boats, bathtubs and corrosion-resistant tanks, and as a precursor to styrenated alkyd resins in paints and coatings .
4.Package and Storage
Styrene is supplied in 200 kg epoxy-coated steel drums, 1 000 L composite IBCs, or 20–25 m³ stainless-steel isotank containers. All packages are nitrogen-blanketed and contain 10–15 ppm 4-tert-butylcatechol inhibitor. Store in a cool, well-ventilated, explosion-proof area below 25 °C, away from sunlight, oxidizers and ignition sources. Avoid prolonged storage above 30 °C; rotate stock every six months and monitor inhibitor level before re-use.
