SBR
Styrene Butadiene Rubber is produced by a technology of cold emulsion co-polymerization based on soaps of rosin and fatty acids. It contains %23.5 of chemically bonded styrene, and is coagulated by styrene and synthetic coagulated. This product is principally used in manufacturing tire, floor converting, footwear, etc.
| Grade | Mooney viscosity (ml 1+4 at 100 °C) | Bounded styrene (%) | Stain |
|---|---|---|---|
| 1500 (non-oil extended) | 46 – 58 | 23.5 | NS* |
| 1502 (non-oil extended) | 46 – 58 | 23.5 | NS* |
| 1507 (non-oil extended) | 32 – 42 | 23.5 | NS* |
PBR
Poly Butadiene Rubber, produced by the solutions polymerization process, based on Cobalt catalysis have a very high elasticity and degree of resistance to dynamic stress and retain these properties even at extremely low temperature.
| Grade | Mooney viscosity (ml 1+4 at 100°C) | Volatile matter (%) | Stain |
|---|---|---|---|
| 1220 (High CIS PBR) | 41 – 49 | MAX 0.75 | Non-Stain |
| 1202 (Low GEL PBR) | 40 – 50 | MAX 2000 | Non-Stain |
