Styrene-butadiene

<p>Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of <a href="/facts/Synthetic_rubber/58Fq4XYx">synthetic rubbers</a> derived from <a href="/facts/Styrene/B8uXm78L">styrene</a> and <a href="/facts/Butadiene/j9W2LxGv">butadiene</a> (the version developed by <a href="/facts/Goodyear_Tire_and_Rubber_Company/QB1Ap5gT">Goodyear</a> is called Neolite). These materials have good <a href="/facts/Wear/2PxRQ1Ke">abrasion</a> resistance and good aging stability when protected by additives.  In 2012, more than 5.4 million tonnes of SBR were processed worldwide. About 50% of car <a href="/facts/Tires/TUgHKMQb">tires</a> are made from various types of SBR.  The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with the <a href="/facts/Thermoplastic_elastomer/bBGfjapB">thermoplastic elastomer</a>, styrene-butadiene <a href="/facts/Block_copolymer/35D97DuV">block copolymer</a>, although being derived from the same monomers.
