Abstract
The present disclosure provides thermal interface materials that are useful in transferring heat from heat generating electronic devices, such as computer chips, to heat dissipating structures, such as heat spreaders and heat sinks. The thermal interface material is soft and has elastic properties post-curing along with high thermally conductive filler loading. The thermal interface material includes at least one long chain alkyl silicone oil; at least one long chain, vinyl terminated alkyl silicone oil; at least one long chain, single end hydroxyl terminated silicone oil; at least one thermally conductive filler, at least one coupling agent, at least one catalyst, at least one crosslinker, and at least one addition inhibitor.
