Technical Specified Rubber
TSR 20 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:
| Limits of TSR 20 grade | Vietnam | ISO | Malaysia | Thailand | Indonesia | ||

| SVR 20 | Test Method | TSR 20 | SMR 20 | STR 20 | SIR 20 | ||
| Dirt (max, %wt) | 0.16 | ISO 249:1995 | 0.20 | 0.16 | 0.16 | 0.20 | |
| Ash (max, %wt) | 0.80 | ISO 247:1990 | 1.00 | 1.00 | 0.80 | 1.00 | |
| Nitrogen (max, %wt) | 0.60 | ISO 1656:1996 | 0.60 | 0.60 | 0.60 | 0.60 | |
| Volatile matter (max, %wt) | 0.80 | ISO 248:1991 | 0.80 | 0.80 | 0.80 | 0.80 | |
