Abstract
PURPOSE: A heat-resistant rubber having improved thermal conductivity and mechanical properties, prepared by adding to a heat-resistant rubber, α-alumina powder and boron nitride powder.
CONSTITUTION: A rubber composition comprising (A) a composite additive comprising α-alumina powder and boron nitride powder, having a boron nitride powder/ α-alumina ratio of 0.2W3.5, and (B) a heat-resistant rubber, wherein said composite additive is present in an amount of 65W78vol%. Examples of the α-alumina powder which can be used include electrofused alumina, calcined alumina and sintered alumina. Among those aluminas, high purity alumina is preferred from a point of electric insulation and those aluminas having a particle diameter of 0.5W100μ are preferred. With respect to the shape of particle, substantially spherical particles are preferred in order to effect high filling.
