Technical Specified Rubber

TSR-10 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). Below you can find an overview of the specifications per grade per region:
