Momentive Performance Materials PolarTherm boron
nitride (BN) powder grade PT110 is a large single- crystal powder in the typical hexagonal platelet
(graphite-like) shape. PT110 possesses an average particle size of ~45 μm and a low surface area of ~0.6 m2/g.

The high-temperature processing and single-crystal
nature of grade PT110 gives it a high thermal conductivity within the particle.

A special grade, PT111, which is screened to remove
+200 mesh particles (> 74 μm) is also available.

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:

Gapfillersandunderfills

Potting and molding compounds

Silicone and other compliant pads

Liquid encapsulants

Compounded thermoplastics
