Abstract
PURPOSE: To provide title compsn. useful as insulating material when heat-generating elements are held and fixed to electronic apparatus, obtd. by mixing organopolysiloxane, boron nitride, low molecular organopolysiloxane and hardener.
CONSTITUTION: Thermal conductive silicone rubber compsn. can be obtd. by mixing (A) 100pts.wt. of organopolysiloxane of formula I (wherein R is substd. or unsubstd. monovalent hydrocarbon gp., a is 1.85W2.1, examples of R are methyl, ethyl, propyl, allyl, cyclohexyl, tolyl), (B) from 100W1000pts.wt. of boron nitride having powdery crystal structure and particle size of from 3W200μm, (C) from 1W50pts.wt. of low molecular organopolysiloxane of formula II or III having a boiling point below 250°C and (D) a hardener such as benzoyl peroxide.
