Boron Nitride fillers from 3M offer a way of dramatically increasing thermal conductivity of polymer composites. Finished parts can achieve up to 10W/mK in-plane and 4W/mK through-plane. As a material it is highly electrically insulating and lightweight, certainly benefiting select applications in electronics and transport. Miniaturization of electronic components and a rapid growth in electric battery technologies have been key drivers in the success of this material, although these are just two sectors amongst a diverse range of use cases.

Boron nitride is also widely used in high temperature lubrication applications, including where incidental food contact is required.

3M offer a unique range of platelets, flakes and agglomerates - each suited to a different application. Get in touch with the technical sales team at Lawrence Industries to see how we can help with your thermal conductivity project.

Features


    • A range of particle size distributions and morphologies available (platelet, flake, agglomerate)

    • Low density (1.2-1.6 g/cc)

    • High electrical resistivity (> 1015 Ohm.cm)

    • High thermal conductivity (400 W/mK in-plane)

    • Low Mohs Hardness (Mohs < 2)

Benefits


    • Formulate polymers with thermal conductivities suited for high performance heat dissipation requirements

    • Lightweight nature means a small increase in part density when compared to other inorganic additives

    • Extremely lubricious and soft so low wear on equipment

    • Excellent pourability and low dusting

    • Reductions in cycle times for injection moulding due to rapid cooling

Typical Applications


    • High capacity batteries

    • Thermal interface materials (TIM) in electronics

    • LED lighting technology - secondary heat sinks and TIM

    • High temperature lubricants

    • Motors, generators and transformers
