Details

Highlights
  • Single platelets for increased in-plane thermal conductivity
  • Excellent for thermally conductive thermoplastics and thermosets
  • Available in grades optimized for injection molded parts
  • Highly crystalline particle sizes start at 0.5 - 15µm
  • High electrical insulation properties with low Dk and Df

3M™ Boron Nitride Cooling Filler platelets are single boron nitride particles that orient during processing of polymer compounds, and deliver high heat spreading capabilities to finished parts. These platelets are excellent for helping improve in-plane thermal conductivity of thermoplastics and thermosets, and are available in grades that are a better option for injection molding applications. Highly crystalline particles are as small as 0.5 µm. Electrically insulating platelets are available in all-purpose grades for a variety of applications. 3M BN cooling filler platelets can be an alternative to mineral- and oxide-based compound fillers.

    3M BN cooling filler platelets are a great choice for applications requiring high in-plane heat spreading capabilities in thermoplastics. Some grades of platelets are particularly better for thermosets and can be used in potting resins as well as thermal pads and thin films. Several grades are available specifically for the flowability and processability required for extruded and injection molded plastic parts.

    A complete selection of 3M™ Boron Nitride Cooling Fillers includes platelets, flakes and agglomerates to meet a full range of performance specifications for in-plane and through-plane thermal conductivity.

Grades of 3M™ Boron Nitride Cooling Filler platelets

  • 3M™ Boron Nitride Cooling Filler Platelets CFP 003E, 003, 006, 0075, 009 and 012
    CFP 003E, 003, 006, 0075, 009 and 012
    All-purpose grades for injection molded parts.
  • 3M™ Boron Nitride Cooling Filler Platelets CFP 001 and 003SF
    CFP 001 and 003SF
    These grades are preferred for thin films of <25 µm, fibers, fine channels and motor windings. CFP 003SF has a controlled top size.
  • 3M™ Boron Nitride Cooling Filler Platelets CFP 012P
    CFP 012P
    Spray-dried boron nitride platelets for excellent processability, flowability and high dosing velocities for extruded and injection molded parts.
  • 3M™ Boron Nitride Cooling Filler Platelets CFP 007HS
    CFP 007HS
    These platelets are ideal for thin films of <50 µm due to controlled top size. They deliver higher reflectivity and increased in-plane thermal conductivity for thermal pads.
