Beschreibung
Zusammenfassung:	A thermally conductive adhesive is provided. The thermally conductive adhesive includes a polyolefin block-containing copolymer, a tackifier, and a thermally conductive filler. The thermally conductive adhesive is a crosslinked pressure sensitive adhesive, plus exhibits a high elongation at break. Additionally provided are thermally conductive articles, including a thermally conductive adhesive on a substrate and a thermally conductive pad. A method of making a thermally conductive adhesive is also provided, including exposing a composition to radiation to crosslink the composition. L'invention concerne un adhésif thermoconducteur. L'adhésif thermoconducteur comprend un copolymère contenant un bloc polyoléfinique, un agent poisseux et une charge thermoconductrice. L'adhésif thermoconducteur est un adhésif sensible à la pression réticulé et présente un allongement à la rupture élevé. L'invention concerne en outre des articles thermoconducteurs, comprenant un adhésif thermoconducteur sur un substrat et un tampon thermoconducteur. L'invention concerne également un procédé de fabrication d'un adhésif thermoconducteur, comprenant l'exposition d'une composition à un rayonnement pour réticuler la composition.
