Industrial curing materials, consist more 200 raw materials. The main compound of these products, materials such as a rubber (synthetic and natural), carbon, silica, soot, sulfur, steel cord, oxidants and so on. Usage of rubber in production of tire is the property of changing shape during pressure and returning state when pressure is released. Carbons
are used to prevent industrial tires from cracking, Also, silica can provide tear and cut resistance to the compound of tire. The presence of soot in the rubber composition can increase the abrasion resistance of tire. Sulfur is an important chemical element that adding it to rubber
compounds can increase the thermal resistance of rubber. Metal reinforcements such as steel cord also increases the strength of certain types of tires. On the other hand, oxidant is one of the protectors that can reduce tire erosion by oxygen.
