MASTERBATCH COMPRISING BORON NITRIDE, COMPOSITE POWDERS THEREOF, AND COMPOSITIONS AND ARTICLES COMPRISING SUCH MATERIALS

A masterbatch composition comprises a composite of a polymer resin material and boron nitride. The masterbatch composition can be in the form of a powder or particles. The masterbatch composition can impart improved properties such as wear resistance, thermal conductivity, compressibility, etc., to...

Beschreibung
Zusammenfassung:	A masterbatch composition comprises a composite of a polymer resin material and boron nitride. The masterbatch composition can be in the form of a powder or particles. The masterbatch composition can impart improved properties such as wear resistance, thermal conductivity, compressibility, etc., to a composition or article formed from the masterbatch composition. In one embodiment, the masterbatch composition can be used to form a brake pad composition and provides a brake pad with improved properties compared to a composition formed by dry blending the separate boron nitride and resin materials.
