Chapter 5.12 Styrene General description Styrene (vinylbenzene, styrole) is a colourless, viscous liquid with a pungent odour and tendency to polymerize. Its chemical structure is C6H5.CH=CH2 and its molecular mass 104.15. Styrene is slightly soluble in water, soluble in ethanol and very soluble in benzene and petroleum ether. Sources

2014-11-15 · The styrene levels during this process are well below the current UK TWA limit (100 ppm) with just two brief excursions above the proposed EU TWA limit (20 ppm). The peaks correspond to the resin and gel-coat preparation (open vessel mixing) steps which could be eliminated with closed mixing systems.

This derivative of benzene is a colorless oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 25 million tonnes of styrene were produced in … Classification of CMRs in the EU is based on the strength of evidence showing that they present one of the CMR types of hazards to human health. The new EU legislation regarding Classification Labelling and Packaging of substances – the CLP Regulation 1272/2008 – uses the hazard categories in Table 1 for substances and for mixtures that contain CMRs. Styrene can accumulate static charges; hence, special attention should be paid to take precautionary measures against static discharge (spark hazard) (refer to Appendices 3, 4, 5 and 6 for more details). 9 2.

Styrene is a monomer used in polystyrene and many other varieties of plastics. Styrene-6,8-oxide is used to make epoxy resins (non-food contact), but it can also be formed in styrene-containing plastics through oxidation of styrene monomer. Read more.
