Advanced Engineering Material
Grade GPBN 1005
GPBN 1005 is a premium-grade Hexagonal Boron Nitride powder designed for advanced industrial applications requiring excellent thermal conductivity, electrical insulation, lubricity, and high-temperature stability. It is especially suitable for thermally conductive plastics, coatings, composites, adhesives, sealants, potting compounds, and electronic thermal management systems.
Boron Nitride is often known as a “white graphite” because of its unique layered crystal structure, smooth lubricating behavior, and excellent heat dissipation properties. Unlike graphite, Boron Nitride provides complete electrical insulation, making GPBN 1005 ideal for electronic, electrical, automotive, coating, and high-performance engineering polymer applications.
Modern industries require materials that can manage heat without compromising electrical safety. GPBN 1005 helps formulators improve heat transfer while maintaining dielectric performance, making it a valuable functional filler for high-performance systems.
Thermal Flow Management
High thermal conductivity improves structural heat dissipation in polymers, composites, and thermal interface layouts.
Dielectric Performance
Excellent electrical insulation parameters and good dielectric properties prevent high-frequency tracking failures.
Tribological Smoothness
Smooth lubricating effects combined with an extremely low abrasive nature compared to conventional ceramic fillers.
High Thermal Stability
Chemical inertness supports superior dimensional stability in thermally loaded, high-stress commercial systems.
Hexagonal boron nitride is recognized for combining thermal conductivity with electrical insulation, which makes it useful in heat spreaders, thermal interface materials, and polymer-based thermal management systems. (Precision Ceramics)
1. Thermally Conductive Plastics
Used as a functional filler in engineering plastics to improve heat dissipation while preserving electrical insulation. It is suitable for configurations where heat build-up must be controlled without making the base polymer electrically conductive.
2. Thermal Interface Materials (TIM)
Suitable for use in high-performance thermal interface materials where controlled heat transfer is required between electronic subcomponents and cooling heat sinks.
3. Coatings & Paint Systems
Implemented in specialty coatings where heat resistance, lubricity, and thermal management are required. Its ceramic nature and smooth platelet layout make it useful in release finishes and protective matrices.
4. Adhesives, Sealants & Potting Materials
For electrical and electronic assemblies, GPBN 1005 improves thermal pathway dissipation within chemical adhesive formulations without sacrificing dielectric limits.
5. Lubricating & Release Applications
Due to its layered structure, Boron Nitride provides lubricating and boundary release protection. Ideal where low friction, clean release, and high-temperature stability are required.
Boron nitride powders are commonly used as fillers in polymers for thermal management because they can improve heat dissipation while maintaining insulation. (Boron Nitride Solutions)

Typical Dosage Guidance
The dosage of GPBN 1005 depends on the required thermal conductivity, viscosity, processing method, and final application.
Suggested Starting Level: 5% to 30% depending on formulation type and performance target. For high thermal conductivity applications, higher loading levels may be evaluated with suitable dispersion, resin compatibility, and viscosity control.
Processing Recommendation
For best performance, GPBN 1005 should be dispersed uniformly into the resin, coating, adhesive, or polymer system. Proper wetting and dispersion are important to achieve consistent thermal performance and smooth application properties.
