Abstract:
1. A thermally-conductive interface interposable intermediate a first heat transfer surface and an opposing second heat transfer surface to provide a thermal pathway therebetween, said interface comprising a thermally-conductive compound formed into a layer which is conformable between the first and second heat transfer surface, said compound comprising an admixture of: (a) a polymeric constituent forming a continuous matrix in said layer, said matrix being form-stable at normal room temperature in a first matrix phase and conformable between the first and second heat transfer surface in a second matrix phase, and said matrix having a matrix melting or glass transition temperature above normal room temperature from said first matrix phase to said second matrix phase; and (b) a dispersed constituent forming discrete domains within said matrix, said domains being form-stable at normal room temperature in a first domain phase and conformable between the first and second heat transfer surface in a second domain phase, and said domains having a domain melting temperature above normal room temperature from said first domain phase to said second domain phase, said domain melting temperature being between about 40-80° C.
