| Grade | Mooney Viscosity [ ML 1+4, 100 ° C ] |
Crystallization Rate |
Other Characteristics |
| GS | 40 - 50 | Slightly Slow | Non-staining, sulfur modified basic G type with best tear strength and flex resistance |
| GRT | 40 - 54 | Slow | Good low temperature properties G type with best tack for frictioning application |
| SND16 | 32 - 39 | Slow | Lower viscosity version of GRT |
| GW | 37 - 49 | Slow | Sulfur modified G type with better heat and compression set resistance than GS and GRT |
| SND46 | 45 - 60 | Slow | More peptizable when milled for sponge products |
