Abstract
The physical morphology and surface properties of a mineral filler is investigated with reference to the affect this has on the reinforcing effect when used in silicone rubber formulations. Results of tests are discussed which indicate that the size, area, shape and state of aggregation of the filler is influential in determining its reinforcing affect in silicone rubber. Fumed silica, precipitated silica and crystalline quartz were chosen in order to compare the influence of the crystalline state of the filler on its reinforcing effect. It was found that there was no direct connection between the crystalline state of the filler and the reinforcing effect, but that this did indirectly affect the reinforcing capability by changing the shape and thus surface energy of the filler. 8 refs.
