摘要
A heat radiation sheet includes a low-hardness insulating heat-radiation layer and a high-heat-radiation insulating layer. Each of the low-hardness insulating heat-radiation layer and the high-heat-radiation insulating layer is formed by mixing a thermoplastic elastomer (TPE), a thermally conductive filler, a flame retardant additive, a process oil, and an additive. A method of manufacturing a heat radiation sheet having a double-layered insulating structure, includes: a first step of forming a mixture by mixing a thermoplastic elastomer (TPE), a thermally conductive filler, a flame retardant additive, a process oil, and an additive; a second step of melt-extruding the mixture at a temperature of 120 □ to 300 □ by a melt extrusion apparatus to from a melt extrudate; a third step of cutting the melt extrudate into a pellet form; and a fourth step of sheeting through melt-extruding the pellet into a sheet form by a melt extrusion apparatus.
