Tires contain around 15 different kinds of rubber in many combinations for different kinds of structure, traction and heat resistance.
Rubber alone doesn’t have the properties that require to make tires. So, many chemicals are mixed in with the rubber. Chemicals help make tires temperature resistance, durable and strong.
Use of the major chemicals in Tires Manufacturing:
Here are the major components of Tire and Rubber manufacturing.
In tire, manufacturing Sulfur is the major component. Its use is in the vulcanization of rubber that makes the tires hard as well as heat resistant. The use of Sulfur is in the manufacturing of most of the tire types. There is an exception when some specific type of tire and rubber are required.
Some tires contain up to 30% of black carbon. Carbon black is the purest form of carbon that is in use in powdered form in tire and rubber manufacturing. It also makes the tire stronger by acting as a reinforcer. It helps tires and rubber from UV rays and from been erode away due to friction on the road.
Tires are not all made from natural rubber. Styrene-butadiene rubber is in use on large scale in tire and rubber manufacturing industry. Synthetic rubber is more pure and cost-effective. Many forms of synthetic rubber are in use for the production of tires. Exact formulation depends on the need or use of the rubber or tire.
Silica helps to reduce the resistance that occures on rolling of the tire. Less friction means the more longevity of tires. Moreover, it helps in two ways, cost-effective as you don’t need to replace tires for long time. Additionally, it helps increse fuel economy as less resistance means lesser power required to move the car. Bis (triethoxysilylpropyl) tetrasulfide is also used in conjunction with silica to make the silica bond to the rubber.
