Polymers are widely used in various activities of life.They are now good alternatives of conventional materials like wood and cotton.(Gunasekaran et al., 2007) Blending of two or more types of rubber is a useful technique for preparing and developing material with properties superior to those of individual constituents.Polymers have many advantages over these materials but also polymers have disadvantages.

Polymers are widely used in various activities of life. They are now good alternatives of conventional materials like wood and cotton.
Polymers have many advantages over these materials but also polymers have disadvantages. In order to overcome these disadvantages as well as introduce new properties, blending technique had been used successfully. (Gunasekaran et al., 2007) Blending of two or more types of rubber is a useful technique for preparing and developing material with properties superior to those of individual constituents. Moreover, each kind of rubber in the blend has its own advantages and specific application due to its chemical configuration and composition. Hence, it is economically easier to blend more than one type of rubber having the desired properties rather than chemically creating of a new elastom
