BN sprays feature high-purity, fine BN crystals suspended within a fast-drying, solvent-based carrier formulation. Available in 13-ounce aerosol cans and made available in 12-can carton shipments, each BN spray can is able to provide about 100 square feet of coverage and is designed to produce a smooth coating with very low binder content.

Nonreactive and nontoxic, BN water-based coatings are available in both 1- and 5-gallon containers. BN water-based coatings can be applied to hot or cold surfaces, while dried coatings can be readily handled, smoothed or polished with a soft, dry cloth. Applying is simple and effective using various commercially available methods, whether by spray, brush, roller or dipping.

Potential applications for BN sprays and water-based coatings include:

  • Metals processing
  • Powder metal processing

CoolFlow BN powders and CoolFX fillers may offer thermoplastic manufacturers an exceptional combination of thermal conductivity, electrical isolation, low density and processability. Testing of heat sink designs made from aluminum versus thermoplastics with CoolFlow BN or CoolFX fillers illustrate these advantages. In convection limited cases, a thermally conductive plastic heat sink cools effectively while being 20% to as much as 60% lighter than the aluminum counterpart. Furthermore, when the filled thermoplastic's higher material cost is offset by the cost of secondary machining and insulation required by aluminum parts, thermally conductive thermoplastic parts filled with CoolFlow BN powders or CoolFX fillers are cost-competitive with aluminum.  

The high-performance CoolFlow BN powders can be formulated in single-crystal grades with mean platelet size of 12 µm, for use in applications like thin films. Other formulations contain a mix of platelets and agglomerates with particles less than 50 µm, for use in plastic extrusion and filled silicone applications. Part designers can utilize the anisotropic nature of these platelets and agglomerates to tailor thermal conductivity directionally.  

In addition to their key beneficial properties of high thermal conductivity and electrical insulation, CoolFlow BN powders and CoolFX fillers are lubricious and nonwetting. Chemically inert and stable at high temperatures, CoolFlow BN powders and CoolFX fillers possess the properties needed to produce cooler, lighter and cost-competitive thermoplastic thermal management components.  

Potential applications for our CoolFlow and CoolFX boron nitride powders may include:  

  • LED light fixtures
  • Consumer electronic devices
  • Aerospace and automotive cooling systems
  • Motor and battery housings
  • Temperature housings
  • Heat exchangers

PBN/PG "printed circuit" heaters utilize PBN as an insulating substrate and PG as the resistive element. In non-oxidizing environments, this combination of unique materials delivers performance advantages not available in conventional thermal systems. PBN/PG heaters operate at 1500°C and higher, and provide superior performance in an ultra-high vacuum. They are also chemically inert to most corrosive gases and liquids, and are unaffected by most molten metals. With their long life, as well as their dimensional and electrical stability, PBN/PG heaters offer high resistance and may enable the use of low-cost power supplies.

 

Mechanically durable and thermally shock resistant, PBN/PG heaters are unaffected by vibration under most conditions and can be tailored to thermal gradients for specific requirements. With an ultra-fast response and low thermal mass, PBN/PG heaters demonstrate a power output of 35 watts/cm 2 (225 watts/in 2 ) and higher.

 

Momentive manufactures heaters as flat plates with surface electrical connections inside the heated area or located outside the heated area on tabs. Heaters can also be made as 3-D elements on CVD PBN crucibles and tubes. PBN/PG heaters have been made for parts as small as 5 mm in diameter, and as large as 800 mm. Multiple, independent zones can be incorporated for flexible thermal management.

 

Potential applications for Momentive heaters and heater assemblies include:

 

  • Epi wafer processing
  • High-temperature industrial and chemical processes
  • PBN and PG custom engineering solutions
