Anhydrite flour

Plastic film tubes

Product Overview

 

TREFIL® is a finely ground and processed natural anhydrite flour (CaSO4) with a tabular structure. Anhydrite makes up the sturdy solid base of gypsum deposits and can be mined separately. TREFIL® is available in various particle sizes and with surface treatment. It is used very effectively as a film anti-blocking agent and as a superior alternative to barium sulphate in high-solid top coats.
