Trefil is the trade name given two types of mineral one based on anhydrite and the other is based on a silane treated phlogopite flour. The anhydrite is formed from an evaporation product from sea water and can be blended with a sulphate. Here the water is driven off to leave a concentrated salt based product which is finely ground to 3-6 microns size. The anhydrite can also be found in gypsum.

The other grade of Trefil starts life as a mica which is crushed, dried and then milled down to a phlogopite flour of particle size 30-50 microns. This is then surface treated with a silane which when added to polymer increases thermal stability.
