Abstract
A silicone rubber composition having excellent workability and extrusion-moldability and capable of giving cured silicone rubber articles having good mechanical properties is proposed, which is prepared by admixing, in addition to the conventional ingredients of an organopolysiloxane gum, a finely divided reinforcing silica filler and a curing agent such as an organic peroxide, a low molecular-weight organopolysiloxane having, in a molecule, at least three silanolic hydroxy groups which serves as a wetting agent of the silica filler so as to improve the compatibility of the silica filler with the organopolysiloxane gum giving a possibility of increasing the amount of the silica filler without adverse influences such as a decrease in the plasticity of the composition.
