Curable silicone elastomer composition |
摘要 |
There is provided herein a curable silicone elastomer composition comprising the following components: (A) 100 parts by weight of a polyorganosiloxane having at least two silicon-bonded vinyl groups per molecule, (B) 1 to 300 parts by weight of fine powders of tungsten carbide and (C) a component for crosslinking of said component (A) selected from the group consisting of (1) a combination of (a) 0.1 to 10 parts by weight of a polyorganohydrogensiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule and (b) 0.000001 to 0.1 part by weight of a platinum catalyst; (2) a combination of said (a), (b) and (c) 0.00001 part to less than 0.1 part by weight of an organic peroxide except from organohydroperoxide; (3) a combination of said (a) and (d) 0.00001 part to less than 0.2 part by weight of the reaction product between said (b) and (c); and (4) 0.1 to 3.0 parts by weight of an organic peroxide except from organohydroperoxide. The composition according to the present invention shows excellent X-xay shielding effect as well as excellent anticoagulative effect, and can give an elastomer of high quality by curing with a broad scope of catalyst systems.
