Boron Nitride Powder PolarTherm* and PolarTherm PTX* Additives

More Effective Heat Dissipation

Enabling heat dissipation at high levels, PolarTherm and PolarTherm PTX boron nitride additives can protect electronic components and assemblies from the damaging effects of heat. Because excessive exposure to heat compromises the service life and reliability of sensitive electronics and electronic components, PolarTherm and PolarTherm PTX boron nitride additives can improve both component lifetimes and cost-effectiveness.   

Compared to other fillers, such as fused silica, aluminum oxide and aluminum nitride, PolarTherm and PolarTherm PTX boron nitride additives are far superior by reaching significantly higher thermal conductivity-even at comparable load levels-under certain conditions.

More About Boron Nitride Powder PolarTherm* and PolarTherm PTX* Additives

Excellent insulators that possess a dielectric constant of 3.9, PolarTherm and PolarTherm PTX boron nitride additives have a high volume resistivity (above 1015 ohm-cm). PolarTherm and PolarTherm PTX boron nitride additives are soft, lubricious materials with excellent flow, adding no additional wear to compounding equipment (like screws, dies and blenders). Use of PolarTherm and PolarTherm PTX boron nitride additives can improve drill life in PCB applications. PolarTherm PTX boron nitride additives are robust spherical agglomerates made of boron nitride crystals that, when loaded into an application like a polymer, demonstrate high thermal conductivity as well as improved through-plane performance.

Potential applications for Boron Nitride Powder PolarTherm and PolarTherm PTX additives include:

  • Thermal greases, adhesives and gels
  • Phase change thermal interface materials
  • Thermal interface films Printed circuit board pre-pregs and laminates
  • Electronic molding compounds
  • Underfills
