About Natural Rubber

TSR which is also known as block rubber is graded according to precise technical parameters such as dirt content, ash content, nitrogen content, volatile matter, and properties of the rubber such as its Wallace Plasticity (PO) and its Plasticity Retention Index (PRI).

The TSR grades most widely used by the tyre and rubber industry are the TSR-10 grades which are originated from West African Region which are known as SIR20, STR20 and SMR20 respectively from Indonesia, Thailand and Malaysia.
