Enhanced performance, reliability and energy savings in your
automotive, electrical and electronic components
SAINT PAUL, Minn., Sept. 9, 2021 /PRNewswire/ -- 3M (NYSE:
MMM), a leader in high-performance polymer additives, has expanded
their line of boron nitride cooling fillers applicable to a wide
array of automotive, electrical and electronic devices and
components.
The new grades from 3M are:
- Boron Nitride Cooling Filler Agglomerates CFA 100
- Boron Nitride Cooling Filler Agglomerates CFA 150
Both consist of soft boron nitride agglomerates used to enhance
isotropic thermal conductivity. They provide better through-plane
conductivity than platelets or flakes, and their softness helps
facilitate low impact on viscosity and easy processing that is less
abrasive on equipment.
Boron nitride cooling filler agglomerates from 3M can be added to potting resins, conformable
TIM foils or pads and other applications where isotropic thermal
conductivity is important. They are also used for bond lines of
150–200 µm (100 grade) and 200 µm or above (150 grade).
Background
To maintain long-term reliability and
efficiency, many modern devices require advanced materials to
transfer excess heat and dissipate it to the surrounding air.
Examples include laptops and smartphones as well as high-capacity
batteries and motors used in electric/hybrid vehicles.
From phones to automobiles, more and more products are
incorporating 5G components, requiring more electronics, which in
turn generate more heat. For resin suppliers, compounders and
component manufacturers, the challenge of thermal management has
never been greater.
About Boron Nitride Cooling Fillers from 3M
3M
designed its boron nitride cooling fillers to address this
challenge. Boron nitride is a material consisting of boron and
nitrogen well-known among chemists for its thermal stability and
conductivity.
3M utilizes these properties to
produce a family of lightweight ceramic fillers that, when added to
polymer compounds, enhance thermal conductivity while maintaining
or improving electrical insulation. Boron nitride cooling fillers
from 3M can achieve high heat removal
while also solving electrical insulation, viscosity and dielectric
property requirements. The multifunctioning properties of boron
nitride as a filler can also help eliminate the need for metal heat
sinks and additional insulation layers, helping you reduce
component size, weight and system cost.
With boron nitride cooling fillers, small plastic
components—including those with complex geometries—can dissipate
heat effectively and achieve long-term reliability and performance.
These fillers from 3M facilitate a
range of thermal conductivity from 1 to 15 W/m·K depending on the
materials and application requirements.
Boron nitride cooling fillers can be added to thermoplastics,
elastomers, thermosets and more. They are gentle on tooling and can
be safely used in compounding, extrusion and injection molding
processes.
