100 200 325 mesh White Diatomite Powder for filter aid and functional filler

Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, mainly composed of ancient diatom remains. Its chemical composition is mainly SiO₂, containing a small amount of Al₂O₃, Fe₂O₃, CaO, MgO, K₂O, Na₂O, P₂O₅ and organic matter. The main uses of diatomite are filter aids, fillers, adsorbents, catalytic carriers, environmentally friendly building materials and so on.

Advantages of Diatomite

Excellent Filtration Performance

Diatomite powder has a high surface area and porous structure, making it an effective filter aid. It helps to remove impurities and particles from liquids, improving the clarity and quality of the filtered product. The different mesh sizes (100, 200, 325) allow for fine filtration, depending on the application.
Lightweight and Low Density

Diatomite powder is naturally lightweight and low in density, which makes it easy to handle and apply. Its low density also contributes to better filtration rates and efficiency when used as a filler or filter aid in various industries like food, beverage, and pharmaceuticals.
Versatile Functional Filler

White diatomite powder is widely used as a functional filler in products like paints, coatings, rubber, and plastics. It enhances the durability and performance of the final product by providing additional strength, reducing weight, and improving thermal stability and resistance.
Eco-Friendly and Sustainable

Diatomite is a naturally occurring mineral, making it an environmentally friendly option for filtering and as a filler material. It is non-toxic and biodegradable, which makes it a preferred choice for applications that prioritize sustainability and green practices.
