SILICA,ITS PREPARATION AND ITS USE IN REINFORCING ELASTOMERS |
| 摘要 |
Silica characterised in that it is in bead form and has a BET surface area of between 60 and 130 m<2>/g, a relative density varying between 0.28 and 0.37 and a total pore volume of between 1.6 and 3.3 cm<3>/g. This silica can be employed especially in the reinforcement of elastomers. |
