Abstract: The invention in one aspect relates to an anti-chafing composition with improved efficacy, in one embodiment, comprising an effective amount of boron nitride suspended in a dermatologically acceptable carrier vehicle. Another embodiment relates to an anti-chafing composition in the form of a powder or a stick containing boron nitride. The present invention also relates to a method of inhibiting or reducing chafing to the skin by topically applying an effective amount of such anti-chafing composition to the skin or to a surface to be in contact with the skin.

Abstract: 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.

Abstract: A topical composition with a sustained softness feel to the skin, comprising an effective amount of boron nitride suspended in a dermatologically acceptable carrier vehicle, wherein the composition suitably adheres to the skin, leaving a coating layer comprising boron nitride particles. The present invention also relates to a method of massaging by applying the composition of the present invention on the body part to be massaged, and massaging the part coated with the composition of the invention.

Abstract: The present invention is directed to enhanced compositions that facilitate the pulling of cables through conduits. In one embodiment, the composition comprises a sufficient amount of boron nitride, which, upon application onto the cable surface, allows the cable to be pulled faster and/or with less force through the conduit than without the boron nitride present. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface. Lastly, the invention relates to an apparatus for distributing a cable-pulling composition comprising a block of boron nitride onto a cable as it is being pulled through a conduit.

Abstract: 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.

Abstract: An anti-seizing composition that facilitates securing fasteners in an assembly, e.g., a nail that is driven by a hammer or a threaded nail or screw that is screwed into a coupling, a nut, or a building block, etc. In one embodiment, the composition comprises a sufficient amount of boron nitride, which upon application on the contact surface of the fastener, allows the fastener to be quickly secured without seizing and/or galling. The invention further relates to a method for securing fasteners in an assembly by applying an effective amount of boron nitride powder composition onto the contact surface of the fasteners, i.e., the pointed end or the threaded surface of the shank.

Abstract: A method of forming pellets or agglomerates of high density boron nitride from high purity hexagonal boron nitride by crushing the high purity hexagonal boron nitride into boron nitride particles extending over a size range of at least 100 microns with the majority of the particles having a particle size above 50 microns and cold pressing the crushed particles into a compacted form. The compacted form is then granulated into a granulated powder and again cold pressed to form pellets or agglomerates of boron nitride particles with the operations of cold pressing and granulation occurring in one or more stages.
