摘要：
Molded silicone rubber unitary bodies of a carbon black containing portion and a portion containing substantially no carbon black which is obtained from a platinum catalyzed addition reaction composition are useful as keyboard pads, zebra-type connectors, and electrical joints. These molded bodies can be made by tightly contacting the uncured composition containing substantially no carbon black with a cured silicone rubber containing the carbon black and then heating to cure.
