Blanc Fixe N4 is natural, fine, high grade crystalline barium sulfate powder. It has acid and alkali resistance, high temperature resistance without losing any property including gloss, whiteness, etc. Blanc Fixe N4 is one of the most used conventional functional filler and inorganic additive worldwide.
Applications
Blanc Fixe N4 is used in many industries for its superior properties.
Coatings: Industrial, marine and powder coatings, etc.
Plastic and rubber: In PVC, PP, PE, PMMA, PUR, ABS, PET manufacturing, it ensures better results than CaCO in terms of mechanical strength, resistance to weathering, aging and chemicals, with noise and 3 vibration suppression in applications.
Blanc Fixe N4 can also find usage areas in paper production (as filler), vehicle brake pads (high resistance to heat), batteries (improves the efficiency of cathod process, etc.) and concrete (as radiation shield against X rays in hospitals,nuclear reactors, etc.).
