If the viscosity is less than 0.5 poise, the blended silicone oil will easily come off, whereas if it exceeds 20 poise, it will easily bleed from the rubber, so both are not preferred. The amount added needs to be in the range of 4 to 230 I), and about 7 to 16% is particularly suitable.

The mixing ratio of (A) uncured silicone rubber composition and (B) silicone rubber composition is 8:
A ratio of about 2 to 4:6 is suitable.
