Rubber Tire ( car ) - Research Paper Example

The materials can be stretched severally to almost double its original size, and upon being released, it will return almost to its original length. Rubber can be produced from two basic raw materials, natural rubber or synthetic rubber. With the objective for improvement, in accordance with customer and regulatory requirements, how a car tire chemical composition is reported through the IMDS system. The introduction of IMDS brought about introduction of pseudo-substance basically for tire. Guidance document clarifies how the pseudo- substance should be used in the IMDS system in order to describe the chemical composition of tire.

Production of car rubber is classified into two basics steps, production of rubber itself and processing into finished goods. In the first step of rubber production, it can be produced naturally by use of an agricultural crop or synthetic rubber made from petroleum products. Natural rubber is acquired from the rubber tree (Hevea brasiliensis) as latex. This is a runny, milky white liquid which is tapped from the bark of rubber tree. Latex is a colloidal dispersion of solid particles of the polymer polyisoprene in water.

The molecules of this compound are loosely joined making long, tangled chains. These molecules of chain when pulled apart untangles easily but springs but together once released and this brings about the characteristic of rubber being elastic. Many tanks are used to collect latex, blending the yield of many trees. (Wiley) General Natural car rubber currently accounts for about 30% to 40% of the total elastomeric part in a car tire, but in the case for a truck is 60% to 80%. The procedure of recovering this natural rubber from latex involves a process called coagulation.

This process is carried out by adding acid such as formic acid (HCOOH). Coagulation takes about 12 hours. The coagulum, which is now soft solid slabs, is then squeezed through a series of rolls which removes most of the
