Polymer Materials and Its Properties

Abstract

The technological process of rubber blend preparation plays an important role in the product quality, and mainly in traffic security. Nevertheless, after more than two hundred years of tyre production, the technology of rubber blend mixing is still a current and intensively developed process. The principle of rubber blend preparation in mechanical mixing is implemented by screw mechanism and extrusion of blend manipulated in such way. The success of the whole technology depends on proper mechanical construction of the masticator’s components for every mixture. Nowadays the polymer materials used in rubber or automotive industry are submitted to new research activities by the miscellaneous angle of vision. Of coarse the final purpose is to provide the best required properties. Tire as a composite imply a lot of materials which have quite disparate properties and are able to appear as unit – consequently they are up to required standard. For example in areas of safety characteristics as an (wet road holding, tire grip, stability), the achievement of high speeds, low power consumption (rolling resistance), low noise level, comfort, attractive design and the tendency of increase lifetime (abrasion resistance, ozone and heat ageing) of these products with a purpose of economical and protection the environment. The interest in polymer materials and its application rising, e.g. in Audi A6 there is represented mass percentage contribution of polymer materials nearly 14 % on the present.
