TSR 20 :-
This grade of natural rubber  is Technically  Specified  Block Rubber (TSR), equivalent to SMR 20, STR 20, SIR 20, ISNR 20 etc in other rubber producing countries. In Sri Lanka this grade is called Sri Lanka Standard Natural Rubber 20 (SNR 20). TSR 20 or our SNR 20 is a large volume grade of TSR, produced mostly from field coagulum and or a blend of field coagulum with lower grades of RSS and or un smoked sheets. It has good processing characteristics and physical properties coupled with low viscosity and easier mixing characteristics.
