A low viscosity filler boron nitride agglomerate particles having a generally spherical shape bound together by an organic binder and to a process for producing a BN powder composition of spherically shaped boron nitride agglomerated particles having a treated surface layer which controls its viscosity.

Boron nitride particles of spherical geometry and process of making

A boron nitride composition comprising at least two different boron nitride powder materials having different properties, e.g., surface areas, particle size, tap density, etc.

Mixed boron nitride composition and method for making thereof

A thermal interface material is constructed from a base matrix comprising a polymer and 5 to 90 wt. % of boron nitride filler having a platelet structure, wherein the platelet structure of the boron nitride particles are substantially aligned for the thermal interface material to have a bulk thermal conductivity of at least 1 W/mK.

Thermal interface materials and methods for making thereof

Boron nitride particles of spherical geometry and process for making thereof

A boron nitride composition having its surface treated with a coating layer comprising at least one of a silane, a siloxane, a carboxylic derivative, and mixtures thereof, wherein the coating layer adheres to at least 10% of the surface of the boron nitride. The boron nitride powder surface is first treated by either a calcination process, or by coating with at least an inorganic compound for the surface to have a plurality of reactive sites containing at least a functional group that is reactive to at least one functional group of the final coating layer.

Enhanced boron nitride composition and compositions made therewith

A boron nitride composition having its surface treated with a coating layer comprising a zirconate coupling agent. The boron nitride composition can be used as fillers in polymeric compounds at levels of up to 90 wt. %, giving thermal conductivity of up to 35 W/mK.

Enhanced boron nitride composition and polymer-based compositions made therewith
