When you use MicaFort Muscovite Mica in tyre moulds, this will enable easy release of the rubber car tyre.
MicaFort disperses well in the liquid coating used to spray the internal mould surface and provides a beneficial anti-adherence effect. The lubricity of MicaFort is far superior to other minerals used in this tyre release coating applications.
In our dedicated production facilities, LKAB Minerals have developed MicaFort products with:
These features combined provide the slip and lubrication which is essential for mould release agents they use in the production of rubber tyres.
LKAB Minerals have a complete understanding of the sensitivity of these coatings and can offer customers a consistent Mica product. We provide tight control of the particle sizing of the grades. As a result of this, we strictly control the top cut to prevent nozzle blockages and manufacturing stoppages.
We manufacture and supply a portfolio of Micas which you can use in this application. Wet ground MicaFort classes provide the best slip and lubricity to tyre release mould coatings.
MicaFort raw materials are selected from global sustainable sources and processed in our European plants.
