Elastomeric foam
摘要:
A simplified method of manufacturing a silicon elastomeric foam comprises mechanically generating a stable froth of an aqueous silicone emulsion, while adding surfactant and thickener, then removing the water from the stable froth. The emulsion consists essentially of anionically stabilized hydroxyl endblocked polydiorganosiloxane, colloidal silica, an organic tin compound, and water, the emulsion having a pH in the range of 9 to 11.5 inclusive. The dried foam is an elastomeric, cellular structure possessing typical silicone elastomer heat stability.
