Product description
Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers.
Key Physical and Chemical PropertiesStyrene monomer is a clear, colorless liquid with a molecular weight of 104.15 g/mol and a density of 0.909 g/cm3. It boils at 145C, has a melting point of -30.6C, and is highly volatile and flammable. Its autoignition temperature stands at 490C, and vapor pressure is 6 mmHg at 20C. Styrene is insoluble in water but mixes readily with organic solvents.
Usage and ApplicationsStyrene is widely used as a chemical intermediate for manufacturing polystyrene plastics, synthetic rubbers, resin, and latex. The materials high purity and reactivity make it valuable for polymerization processes and chemical synthesis in several industries, including packaging, automotive, and construction.
Safe Handling and Storage TipsDue to its volatility and flammability, styrene monomer should be stored in a cool, well-ventilated location away from heat, sparks, or open flames. The product contains an inhibitor to prevent polymerization during storage and transport. Always use appropriate personal protective equipment and follow local regulations for hazardous materials.
FAQs of Hot sale styrene monomer CAS 100-42-5:
Q: How is styrene monomer typically stored and transported safely?
A: Styrene monomer should be stored in tightly sealed 190 kg iron drums or ISO tanks in a cool, well-ventilated area, away from sources of ignition. For transport, especially by sea, it is classified as a hazardous material (UN No. 2055, Hazard Class 3) and contains an inhibitor to prevent polymerization.
Q: What are the main industrial applications of styrene monomer?
A: Styrene monomer is primarily used for manufacturing polystyrene, synthetic rubber, resins, and latex. It acts as a key intermediate in large-scale polymerization and chemical synthesis processes across plastics, automotive, and construction industries.
Q: When should styrene monomer be used for optimal performance?
A: Styrene monomer should be used within its 24-month shelf life and stored under recommended conditions. Using it within this period ensures maximum purity and performance in polymerization and synthesis applications.
Q: Where is styrene monomer commonly distributed or exported from?
A: Styrene monomer is distributed globally by suppliers, exporters, dealers, and manufacturers, including major trading hubs like South Africa. Bulk shipments are typically handled via sea transport due to its hazardous nature.
Q: What precautions are necessary when handling styrene monomer in the workplace?
A: Workers should use suitable protective gear including gloves and eyewear, ensure good ventilation, and avoid open flames. Storage areas must be free from ignition sources and equipped to contain spills, following all local hazardous material regulations.
Q: How does the built-in inhibitor benefit the storage and stability of styrene monomer?
A: The inhibitor in styrene monomer prevents premature polymerization during storage and shipping, enhancing product stability and minimizing the risk of hazardous reactions until the monomer is ready for use.
Q: What are the physical characteristics and sensory attributes of styrene monomer?
A: Styrene monomer is a clear, colorless liquid with a characteristic aromatic, sweet, benzene-like odor. It has a molecular formula of C8H8, a refractive index of 1.5465, and is insoluble in water but dissolves in organic solvents.
