Abstract

PURPOSE:To provide the titled powder composed of silicone powder containing a specific amount of a silicone oil and having an average particle diameter falling within a specific range, having excellent lubricity and shock-absorbing property and suitable as an additive for modifying physical properties of various rubbers and organic polymers, etc. CONSTITUTION:(A) A silicone rubber composition, e.g. a liquid silicone rubber composition curable by condensation reaction and composed of an organopolysiloxane having both molecular chain terminals blocked with OH groups, an organohydrogen polysiloxane having >=2 H atoms bonded to Si and an organic tin catalyst is compounded with (B) a silicone oil having a viscosity of preferably 100-10,000cst of 25 deg.C. The mixture is dispersed in water containing a surfactant and the obtained aqueous dispersion is sprayed into hot air and cured to obtain the objective silicone powder containing 0.5-80wt.% of the silicone oil B and having an average particle diameter of 0.1-20,000mum.
