The styrene-butadiene-styrene (SBS) is a kind of thermoplastic elastomer which has the same elasticity with the rubber in normal temperature, and can be melt to flow at high temperature like plastics, called plastic material. Styrene is named after storax balsam, the resin of Liquidambar trees of the Altingiaceae plant family. In Building Materials in Civil Engineering, 2011 (1) The Styrene-butadiene-styrene (SBS) Modified Asphalt. Melting Points of Polymers in Celsius. In 1839, the German apothecary Eduard Simon isolated a volatile liquid from the resin (called storax or styrax (Latin)) of the American sweetgum tree (Liquidambar styraciflua). The styrene content typically varies between 15 and 40 percent. An example is the 2019 explosion of the tanker Stolt Groenland; in this incident 5,250 metric tons of styrene monomer detonated while the ship was docked in Ulsan, Republic of Korea. Styrene oxide is subsequently hydrolyzed in vivo to styrene glycol by the enzyme epoxide hydrolase.

A storage hazard above 32°C, involved in several industrial explosions caused by violent, exothermic polymerization [Bond, J., Loss Prev.  The U.S. Environmental Protection Agency (EPA) has described styrene to be "a suspected toxin to the gastrointestinal tract, kidney, and respiratory system, among others".  He also noticed that when styrol was exposed to air, light, or heat, it gradually transformed into a hard, rubber-like substance, which he called "styrol oxide".  However, a STATS author describes a review that was done on scientific literature and concluded that "The available epidemiologic evidence does not support a causal relationship between styrene exposure and any type of human cancer". Styrene, 99%, stab. Oct 14th – 16th 2015, nanocon,Brno, Prof. Dr. Arno Behr.

They had also determined that Simon's "styrol oxide" – which they renamed "metastyrol" – had the same empirical formula as styrene.  Furthermore, they could obtain styrene by dry-distilling "metastyrol". They concluded, "The findings have to be interpreted with caution, due to the company based exposure assessment, but the possible association between exposures in the reinforced plastics industry, mainly styrene, and degenerative disorders of the nervous system and pancreatic cancer, deserves attention". In 2012, more than 5.4 million tonnes of SBR were processed worldwide. +Add Attachment The vast majority of styrene is produced from ethylbenzene, and almost all ethylbenzene produced worldwide is intended for styrene production.
