Patent
CA 2418354
The invention relates to rubber blends, which contain microgels and isocyanatosilanes, and to vulcanizates produced therefrom. By adding the isocyanatosilanes, the mechanical properties of the vulcanizates, especially the expansion properties and wear resistance, are improved without reducing the difference of the rebound elasticities at 70 ~C and 23 ~C.
L'invention concerne des mélanges caoutchoutés, contenant des microgels et des isocyanatosilanes, ainsi que des vulcanisats obtenus à partir de ces mélanges. En ajoutant des isocyanatosilanes, on améliore les propriétés mécaniques de ces vulcanisats, en particulier les propriétés d'allongement et la résistance à l'usure, sans réduire la différence des élasticités de rebondissement à 70 ·C et 23 ·C.
