3M™ Boron Nitride Cooling Fillers 50M, Agglomerate, 25 kg Drum

3M™ Boron Nitride Cooling Fillers are trusted across industries for effective temperature control. Downsized, lightweight, and complex geometries require materials that can spread heat within a small space and transfer it to the surrounding air. Plastics are the material of choice, but they are usually not thermally conductive. Adding 3M™ Boron Nitride Cooling Fillers as a filler is an easy way to resolve this issue.

In the consumer electronics sector, 3M™ Boron Nitride Cooling Fillers aid in heat dissipation in mobile devices and televisions. As these devices get thinner, heat dissipation and electrical isolation are more crucial than ever. 3M™ Boron Nitride Cooling Fillers can be easily compounded with thermoplastics for injection moulding or extrusion of pads, LED housings, and heat sinks. One specific focus is in TIM applications – epoxy, silicon, and acrylates – due to their thermal conductivity and electrical insulation capabilities, in addition to having a range of particle distributions and top cut sizes. When used in thermoplastics and elastomers, 3M™ Boron Nitride Cooling Fillers are useful in automotive applications such as batteries and housings for electric and hybrid vehicles, as well as LEDs. When combined with thermosets, they can be directly injection moulded or used in potting resins around electronic components to isolate them from moisture and dissipate heat. 3M™ Boron Nitride Cooling Fillers are used increasingly in applications where the highest electrical insulation is required to also achieve a high thermal conductivity. They are commonly added to polyester, polyimide, and PEEK, where they are useful in high-temperature insulation foils. 3M™ Boron Nitride Cooling Fillers are suitable for use with a variety of foil thickness, from 150 microns to 25 microns.
