Momentive Performance Materials PolarTherm boron nitride
(BN) powder grades PT130, PT131, and PT132 are a new line of powders designed to offer an economical way to achieve
the benefits of PolarTherm technology. These powders make an ideal substitute for aluminum nitride, alumina, and fused silica in applications where improved heat transfer properties are needed.

PT130, PT131, and PT132 are fine hexagonal crystalline powders (>95% -325 mesh) with a range of surface areas to fill a variety of thermal management applications.

Applications:
Momentive PolarTherm BN powders’ unique combination of thermal, electrical, and mechanical properties make them ideal for use in a range of thermal management materials, including:
Gap fillers and underfills
Potting and molding compounds
Silicone and other compliant pads
Liquid encapsulants
Compounded thermoplastics
