what is styrene monomer used for

Styrene molecules also contain a vinyl group (ethenyl) that share electrons in a reaction known as covalent bonding. 132 0 obj <> endobj Styrene (also known as STY, styrene monomer, vinyl benzene, phenylethylene, styrol, styrole, styrolene, cinnamene, styron, and cinnamol) is a clear, colourless to yellow, oily liquid with a sweet smell. China's styrene monomer market continued its downward move since November 17th after the aggressive increase since October. A company official said 1,800 tonnes of styrene was stored in a tank of capacity 2,400 tonnes. Why could the inhibitor not prevent what happened? xref Other materials produced include acrylonitrile-butadiene styrene (ABS) and styrene-acrylonitrile (SAN) resins and account for approximately 16 % of styrene consumption. Styrene is an organic hydrocarbon used to manufacture rubber and plastic components. What is ethylbenzene? Styrene Styrene is a chemical used to make latex, synthetic rubber, and polystyrene resins. In chemical terms, polystyrene is a long chain hydrocarbon wherein alternating carbon centers are attached to phenyl groups (a derivative of benzene). 0000001725 00000 n 0000003003 00000 n In this incident, people were exposed to the gas for a short duration, so there may not be any long-term effects,” Dr Kumar said. Styrene and acrylonitrile monomers can be copolymerized to form a random, amorphous copolymer that has good weatherability, stress crack resistance, and barrier properties. Also known as vinyl benzene, styrene is a colorless liquid that quickly evaporates when exposed to the air. Contributing articles to wiseGEEK is just one of Karyn’s many professional endeavors. Historically, growth in the use of styrene has been good although this growth has slowed with the global economic downturn. By the mid-1940s, GRS production exceeded twice the level of natural rubber production prior to the onset of the war. Styrene is an organic hydrocarbon used to manufacture rubber and plastic components. Would eating off of a Styrofoam plate be harmful? A look at its structure, the kind of industries that use it, and the kind of health hazards experts associate it with: Styrene is an organic compound with the formula C8H8, its molecular structure as pictured. However, in people suffering from respiratory illness such as asthma, and those who have chronic obstructive pulmonary diseases, these conditions may get exaggerated, Dr Kumar said. At LG Chem, an inhibitor tank is attached to the styrene storage tank but it failed to stabilise it in time. Other than direct handling, exposure to this substance may occur from inhaling automobile exhaust, cigarette smoke, and being around building materials that contain styrene. The most recognisable of the styrene-based materials is polystyrene, with nearly 65 % of all styrene used … also a magazine writer and columnist, mainly for health-related publications, as well as the author of four books. Styrene monomer is a basic building block of the plastics industry. Industry information is also available by visiting the following external websites. A substitute was secretly made by producing a copolymer of butadiene and styrene known as Government Rubber Styrene (GRS). It should therefore be stored in a cool, dry, well-ventilated area that is free from the risk of ignition. 0000011953 00000 n How International Emmy winner 'Delhi Crime' came into being, Sonia loses her pillar of support, Cong its key link between past and present, Cyclone Nivar LIVE: 1000 cusecs of water to be released from Chembarambakkam lake, First of Many: Pratik Gandhi revisits Yours Emotionally, An unexplained metal monolith in the US sparks comparisons with '2001: A Space Odyssey', Praise pours in for 11-year-old girl after she rescues shark caught between rocks, Team India goes back to ’92 World Cup kit as new sponsors plays it safe, Yuzvendra Chahal: Ready for a bigger Test, Protecting Article 32: Right to constitutional remedies is the Constitution’s soul, Diet to exercise: FSSAI suggests these post-festival tips to resume a healthy routine, Meet 'Tooter' the Swadeshi answer to Twitter: Everything you need to know, Nus, ISL’s youngest manager, sets tone for the season after opening round, Five things you might not know your Chromecast can do, Dyson Pure Hot+Cool Cryptomic review: The hot air purifier for this oddball year, Gender-based violence was predictable, and preventable, fallout of lockdown, Bihar affirmed Election Commission’s ability to conduct elections that are free, fair — and safe. 0000011883 00000 n Tel: +32 (0)3 205 16 66, We have placed cookies on your computer to help make this website better. Our customers can continue to safely use styrenic polymers for all applications -- when used under normal conditions and in accordance with the Safety Data Sheet. As per the United States Environmental Protection Agency, tests involving acute exposure of rats and mice have shown styrene to have low to moderate toxicity by inhalation and oral exposure. 0000002311 00000 n It is the mucous membrane that is mainly affected by exposure to styrene gas. 0000006346 00000 n The factory manufacures general-purpose polystyrene and high-impact polystyrene, expandable polystyrene, and engineering plastics compounds. The vast majority of styrene is produced from ethylbenzene, and almost all ethylbenzene produced worldwide is intended for styrene production. The temperature has to be continuously monitored, and any exposure to light or heat may result in polymerisation. If temperature rises, inhibitors have to be added to keep the styrene stable. Styrene occurs naturally in the environment and is found in many foods such as coffee, strawberries, and cinnamon. It is also used to make plastic drinking cups and food storage containers. This process is what allows the synthetic chemical to be made into plastics, such as polystyrene, synthetic rubber, and latex. However, it is now derived from petroleum and natural gas by-products with styrene most commonly produced by the catalytic dehydrogenation of ethylbenzene. Styrene is not harmful in the small amounts encountered in everyday products. https://" : " https://"); It is a simple random copolymer.
