Thermal conductive thermoplastic material and its production process

The present invention is thermal conductive thermoplastic material includes at least thermoplastic elastomer , oil and stuffing, and has thermal conductivity over 0.8 W/m-K. The said material is easy to combine with surface of irregular shape, has low heat resistance of 0.1 K-sq in/W at 0.5 MPa. It has 240-hr volatilization rate lower than 0.15 % at 70 deg.c, superior to available thermal conductive paste, and, what is more significant is the excellent reusability of the material. 一种热传导性的热塑性材料及其制造方法，它至少包含热塑性弹性体(如苯乙烯系嵌段共聚物)、油类及填充物，组成物的热传导系数大于0.8watts/m-K。此材料相当容易与不规则形状表面密合，并在0.5Mpa的压力下具有很低的热阻抗值0.1K-in#+[2]/watt。此材料在70℃，240小时下挥发率低于0.15％，比目前的热导膏要好，特别是，该材质有良好的可再利用性。
