摘要： The present disclosure relates to a thermally conductive pressure sensitive adhesive composition, comprising: a) an acrylic polymer component; and b) a boron nitride mixture composition comprising: i. anisotropic boron nitride agglomerates comprising hexagonal boron nitride primary particles, wherein the hexagonal boron nitride primary particles have an average primary particle size d 50 comprised between 1 and 50 micrometer, wherein the anisotropic boron nitride agglomerates have an average agglomerate size d 50 comprised between 50 and 250 micrometer and an aspect ratio greater than 1.5, and wherein the envelope density of the anisotropic boron nitride agglomerates is greater than 1 g/cm3?, when measured according to the test method described in the experimental section; and ii. (optionally), free hexagonal boron nitride primary particles having an average primary particle size d50 comprised between 3 and 50 micrometer; and wherein the content of the boron nitride mixture composition is greater than 15 vol%, based on the volume of the thermally conductive pressure sensitive adhesive composition. The present disclosure also relates to a method of manufacturing such thermally conductive pressure sensitive adhesives and uses thereof.
