RUBBER CHEMICALS TEXTILES STEEL
Tree plantations, in various parts of the world, consisting mainly of the Hervea variety have their sap (latex) collected in cups below small cuts in the trees’ outer bark. The liquid is then coagulated to form solid slabs of natural rubber. Synthetic rubber is produced by the interaction of various chemicals & processe on crude oil.
Carbon Black, produced mainly by burning crude oil in special furnaces, is used in tyre compounds as a reinforcing filler. Other chemicals include sulphur, plasticizers, accelerators and antioxidants.
Materials such as Rayon, Nylon and Polyester form an integral part of many tyres’ carcass construc-tions.
High tensile brass-coated steel cord is used in the construction of a tyre’s breaker belts as well as the carcass ply in many truck tyres.
