SILICONE RUBBER AND THERMOPLASTIC COMPOSITE

摘要

Composites comprising at least one layer of a thermoplastic organic resin and least one layer of a cured silicone rubber can be prepared by injecting a thermoplastic resin into a mold cavity, allowing the resin to harden, injecting a curable liquid silicone rubber composition into a mold cavity that is partially occupied by the hardened thermoplastic resin and then curing the liquid silicone rubber composition. The liquid silicone rubber composition is cured at a temperature from 25 degrees C. up to and including the softening point of the thermoplastic resin, In a preferred embodiment the curable liquid silicone rubber composition is maintained at a temperature of from -60 to +5 degrees C. prior to being injected into the mold cavity.
