Foamable polyorganosiloxane compositions

摘要

Polyorganosiloxane foams are prepared by the volatilization of a blowing agent within a polyorganosiloxane composition that is curable by a hydrosilation reaction and includes as a foam stabilizer a resinous polyorganosiloxane comprising trimethylsiloxy units, SiO4/2 units and a specified class of fluorine-containing siloxane units.
