The Spectrum of Performance: Saint-Gobain’s Engineered Boron Nitride Powder Grades

Saint-Gobain’s boron nitride (BN) powders are not finished products themselves, but engineered grades designed to be used as fillers and additives in customer-made formulations such as lubricants, dispersions, composites, and coatings. Each grade differs in morphology, particle size, and purity to deliver distinct performance characteristics in the final system. By selecting the right BN powder grade, producers can create reliable solutions that meet demanding requirements in metals processing, glass forming, electronics, automotive, aerospace, and beyond. And while these powders are developed primarily for producers, end users interested in BN applications can also be guided toward trusted partners for tailored solutions.

Standard Platelets - A Proven Foundation for Versatility

Standard Platelets are high-purity BN crystals with a tight particle size distribution and no agglomeration. Their anisotropic, plate-like structure enables high in-plane thermal conductivity, effective lubricity, and electrical insulation. Mechanical stability under high shear allows these platelets to withstand compounding and extrusion without degradation.

For manufacturers in North America, local production supports consistent material characteristics and short delivery intervals.

 

Applications by sector:

• Electronics & Thermal Management: Dielectric thermal fillers, potting compounds
• Metals Processing: Mold release agents
• Plastics: Polymer processing aids, lubricant additives
• Consumer & Specialty: Cosmetic formulations

MCFP - Multi-Purpose Fine Powder for High-Temperature Reliability and Value

MCFP is a 97% purity boron nitride powder with a fine particle size of -325 mesh, designed for incorporation into advanced formulations that require reliable high-temperature performance. As a filler, MCFP brings its characteristic lubricity, thermal stability, and chemical inertness into end-use systems such as lubricants, dispersions, or release agents.

With oxidation resistance up to 850 °C in air and stability above 2000 °C in inert environments, MCFP remains effective where conventional additives lose performance. Its non-wettable nature helps prevent adhesion of molten metals and glass, which in turn reduces residue buildup, protects tooling surfaces, and improves process consistency. When integrated into customer-designed products, these properties can contribute to extended tool life, shorter cycle times, and fewer production interruptions.

MCFP is also well-suited for use in lubrication systems. When added as a filler in high-temperature lubricants, dispersions, or pastes, it enhances lubricity under thermal stress and enables smoother operation of moving components. Compared to traditional additives like graphite or MoS₂, MCFP offers the added benefits of being chemically inert, non-toxic, and non-staining, making it a safer and cleaner choice for demanding environments.

 

Its versatility also extends to specialty coatings, refractories, and polymer or ceramic composites, where MCFP improves release, thermal stability, and overall process reliability. Importantly, MCFP is the most economically accessible BN powder grade in Saint-Gobain’s portfolio, enabling manufacturers to design effective, value-driven solutions without compromising technical performance.

 

Manufactured primarily in the USA with supplementary production in other key markets, MCFP ensures reliable supply chain stability for operations with high-volume or time-sensitive requirements. For manufacturers seeking to reduce dependency on imported powder alternatives commonly used in lubricant formulations, MCFP delivers exceptional value as the most economically accessible BN grade in our portfolio—combining proven high-temperature performance with competitive domestic pricing.

Applications by sector:

• Metals Processing: Aluminum extrusion dies, molten metal contact surfaces, crucibles, refractory systems
• Glass Forming: Additive for formulations that coat or protect glass molding tools
• Automotive & Aerospace: Filler in high-temperature lubricants, pastes, and composites for bearings, slides, seals
• General Lubrication: Dry film lubricants, dispersions, and specialty formulations requiring inert, non-toxic additives

Modified Platelets - Tailored for Bonding and Composite Integration

Modified Platelets have a submicron particle size and can be adjusted for purity and oxygen content to improve reactivity and bonding with polymers. These modifications enhance dielectric and thermal performance when integrated into composite systems.

 

Locating production near major composite manufacturing hubs supports shorter supply timelines and consistent material performance.

 

Applications by sector:

• Automotive & Aerospace: Brake pads, friction components
• Plastics & Composites: Thermoplastic fillers
• Metals Processing: Powder metallurgy additives

Spherical Agglomerates - Designed for Flow and Thermal Management

Spherical Agglomerates are clusters of BN platelets bonded into a rounded structure, giving them high flowability, packing density, and isotropic thermal conductivity. This morphology allows for uniform filler dispersion and efficient heat distribution in thermal management systems.

Proximity to electronics manufacturing centers helps maintain minimal transit times and reduce intermediate handling.

 

Applications by sector:

• Electronics & Thermal Management: Thermal interface materials (TIMs), gap fillers, heat sinks, power semiconductors
• Automotive & Aerospace: Thermal interface solutions for batteries and motors
