Product name: Silica for silicone rubber
Advantages of fumed silica in silicone rubber
Super high reinforcement performance, improve the base rubber strength by 40 times;
Greater elongation and tensile strength, avoiding whiting or break;
Higher toughness, hardness and resilience of the rubber body;
Low impact on transparency or clarity;
Better performance on heat resistance, aging resistance and dielectric property;
Excellent thickening & thixotropic properties, shorten the mixing time.
Fumed silica is an ideal reinforcing agent for silicone rubber. The strengthening is fundamentally brought about by silanol groups being interacted with or Si-methyl bonds being radically cleaved into the polymer. The surface silanol groups (Si-OH) of fumed silica react with silicone rubber macromolecule, then generate a silicon rubber molecular adsorption layer on the surface of silica, then a three-dimensional network structure is formed. This structure effectively limits the deformation of the silicone rubber molecular chain, thereby achieving the reinforcing effect.
