Many metals and ceramics are used for the countermeasure against heat of a product. Sumitomo Bakelite combined the high thermal conductivity filler, and developed the heat dissipative resin molding compounds with both thermosetting and thermoplastic resin. The flexibility of form increases, and a weight saving also become possible, and they can be used widely from electronic components to auto parts. There are insulative type and non-insulative type.
