Mica (Muscovite)

TREMICA® muscovite mica (phlogopite also available under TREFIL® 1232 brand name) is a high aspect ratio, platy, particle suitable for use in high temperature plastics and coatings due to its low distortion and crack prevention properties. Mica is also frequently used in anti-corrosion coatings, where it forms an effective barrier through increasing salt and water percolation distance.


    • Naturally occuring muscovite mica.

    • High aspect ratio, platy, lamellar particle morphology.

    • Hardness of 2.5 on Mohs scale.

    • Low oil absorption.

    • Light colour.


    • Reinforces engineering polymers such as nylon, PEEK, PBT, polyurethanes.

    • Little influence on pigments so light colours possible.

    • Increases tensile strength and rigidity in thermoplastic parts.

    • Low distortion in high temperature polymers.

    • Prevents cracking in emulsion based paints and forms an effective barrier in anti-corrosion coatings.

Typical Applications

    • Automotive polymer parts, under bonnet in particular.

    • Emulsion based paints and plasters.

    • Anti-corrosion coatings.

    • Silicate paints.

    • High temperature coatings.

    • Matting agent for powder coatings.
