Silicones
The flexibility or rubber hardness is controlled in both RTV and HTV silicone applications by adding mineral fillers: quartz, cristobalite, nepheline syenite, …

The natural affinity between silicates and silicones and the inertia in relation to acids (incl. acetic acid) are technical benefits. Cristobalite flours have an extremely low humidity and are therefore an advantage in desiccating silicones and polyurethane applications.
