Minerals in plasterboard

Discover the minerals which go into plasterboard.

Mica and Talc are fundamental elements of plasterboard, otherwise known as drywall. It is used as an alternative to plaster for covering existing walls or creating new walls when fixed to frames and studs.

MicaFort, a high aspect ratio mineral filler, improves appearance and stability of drywall-, plaster- and fire resistant wallboards and joint cement. The plate-like particles significantly reduce shrinkage when jointing cement is drying which is essential when joining mica filled wallboards together.

LKAB Minerals Talc products are ’off white’ and therefore more suited for bulk applications where colour is less critical. These applications include plasterboard, roofing, industrial coating applications and plastics.
