A two part curable liquid silicone rubber composition is provided, wherein the first liquid composition and the second liquid composition, when mixed, when cured, yield a silicone elastomer having an elongation at break value of at least 800%. Calculate. The silicone elastomer of the present invention comprises at least one alkenyl group containing organopolysiloxane having two silicon-bonded alkenyl groups per molecule, and at least one diorganohydrogensiloxy-terminated polydiorganosiloxane, per molecule at least one organosilicon crosslinking agent containing at least three silicon-bonded hydrogen atoms, at least one addition reaction catalyst, and at least one filler. Also provided are silicone elastomers that have an elongation at break value of at least 800% and that withstand elongation without breaking. Also provided is an article for a medical device comprising the two part curable liquid silicone rubber composition of the present invention or a cured product of a silicone elastomer. |
