ABSTRACT:
A filler composition composed of metal particles present in the tightest possible packing which are individually coated with a cross-linked polymer layer is provided which has high thermal conductivity and high electrical insulation capacity. Such filler composition is usefull as an addition to resins employed in injection molding and extrusion. A high resistance to abrasion is achieved by the cross-linked coating layers (22,24). A filing degree of about 90 Vol. % is achievable with such a filler composition, and such displays a breakdown voltage greater than about 100 V.
