Thermally Conductive Sheet And Method For Manufacturing The Same
Patent #: 7,018,701
Inventor(s): Shunsuke Yamada, Hajime Funahashi and Junzo Shiomi
Company: Fuji Polymer Industries Co., Ltd.
A polyolefin elastomer mixed with a thermally conductive filler was recently granted a patent. The polyolefin elastomer is a polymer obtained in which an allyl group is present at both terminals polyisobutylene, and volatile components, including residual solvent and an unreacted residual material, contained in the polyolefin elastomer are removed by distillation or reduced-pressure aspiration during or before producing the thermally conductive sheet. The amount of volatile organic gas generated from the thermally conductive sheet per unit surface area is not more than 1000 m/cm2. The amount of volatile corrosive gas generated from the thermally conductive sheet per unit surface area is not more than 10 mg/cm2, and the thermally conductive sheet has a thermal conductivity of 0.5 to 20 W/m·K.
