The hydrogenation of an SBS rubber-whose elastomeric block contains at least 40% of 1.2 units - leads to the formation of an elastomeric segment in which ethylene units alternate statistically with butylene units (with gives it the name SEBS). These materials, which feature an excellent resistance to oxidation and to which large quantities of plasticizing agents and charges can be added, are used for the most part in the manufacture of technical articles, sports items and automobile passenger compartment components. Compounds made with SEBS are characterized by excellent mechanical properties, good resistance to heat and to chemical agents. SEBS compounds offer excellent resistance to atmospheric agents, to UV rays and to ozone, thus representing the ideal choice for outdoor applications and in situations where the product is expected to last a long time. Since 2013, Celloplast GD has also been developing a range of mixes with different concentrations of cork and wood dust (contained percentage in volume from 40 to 65).
