Method for producing silicone rubber powder

Abstract

Powdered, cured silicone rubber in the form of microfine particles is prepared by emulsifying a curable liquid silicone rubber composition in a mixture of water and a surfactant at a temperature of from 0 to 25 degrees C, dispersing the curable composition in water heated to a temperature of at least 25 degrees C and recovering the resultant cured particles. The liquid silicone rubber composition is preferably maintained at a temperature of from -60 to 0 degrees C before being emulsified.
