Abstract
Thermoplastic rubber is used as part of a thermally conductive electrically insulating filled elastomer composition. The filler may be any conventional filler such as hexagonal boron nitride or alumina. The thermoplastic rubber may be crosslinked. The filled elastomer can be molded or pressed into desired shapes.
Claims5
A thermally conductive electrically insulating filled elastomer composition comprising:
- a) a styrene-ethylene-butylene-styrene block copolymer thermoplastic elastomer, and
- b) about 45-70 vol. % thermally conductive electrically insulating filler particles.
