Boron nitride is an excellent heat conductor and electrical insulator with overall cost reduction while improving physical properties at lower loading.

BN for thermoset applications

Boron nitride (BN) is an excellent additive for thermoset applications as well as for thermoplastics applications.

You can consider BN for use in a wide range of resins and applications:

BN for use in a wide range of resins and applications

Boron nitride powders can be used in all forms to enable thermal conductivity while maintaining electrical insulation and b mechanical properties, making BN well suited for use in thermal management applications.

Its hexagonal crystal structure, which is similar to carbon, is also soft and lubricious. Its properties can make it the best overall choice for thermal management. Boron nitride structure

Key features and typical benefits:
