ABSTRACT:
Organosilicon compositions which can be cured to produce elastomers, in particular elastomers suitable for use in the food industry, contain very fine particulate aluminum oxide powder in minor amount. Non-blocking sheets and pellets can be formed from the compositions, and later molded and cured.
