Abstract
The tear strength of cured organosiloxane elastomers can be increased and the compression set value reduced without adversely affecting other physical properties if the composition used to prepare the elastomer is curable by a platinum-catalyzed hydrosilation reaction and contains a mixture of two liquid diorganoalkenylsiloxy terminated polydiorganosiloxanes, one of which constitutes from 96 to 99.5 percent by weight of said mixture and contains the alkenyl radicals only at the terminal positions. The second polydiorganosiloxane contains both terminal alkenyl radicals and from 1 to 5 mole percent of alkenyl radicals on non-terminal repeating units.
