The present invention provides a silica-free liquid silicone rubber composition comprising an organopolysiloxane polymer having a viscosity of from 300 to 100,000 mPa.s at 25° C. The organopolysiloxane polymer comprises from about 10 to 1500 repeating units of the following general formula R<SUB>n</SUB>SiO<SUB>(4-n)/2</SUB>. Each R group is the same or different and is independently selected from monovalent hydrocarbon groups having from 1 to about 18 carbon atoms. N is 0 or an integer from 1 to 4. At least two R groups per molecule are either hydroxyl and/or hydrolysable groups or are unsaturated organic groups when n is 2 or greater. |
