Kieselguhr fillers

Kieselguhr / Perlite (Celatom®)

Diatomaceous earth, also known as kieselguhr, is a versatile mineral. It is used in many filtration applications but also widely used in paint.

Celatom® Mineral Natural (MN) diatomaceous earth (DE) grades are known for their natural, high quality and purity, MN grades are used in agriculture, home & garden, automotive components, ceramic and fertilizer industries. They can be used as a performance additive, carrier or filler in an unlimited number of applications.

We offer Celatom® diatomaceous earth for the use in beer and liquid foodstuff filtration, coatings and adhesives and for usage in the foundry industry.

Advantages of Celatom® diatomaceous earth in filtration are that all Celatom grades are based on sweet water diatoms resulting in very pure products.

We also offer an acid washed grade for high end applications, including pharmaceuticals.

Advantages of using Celatom® in coatings are high whiteness and low cost,  resulating water permeability, matting effect and much more.

Celatom® Perlite is a hydrated, naturally-occurring volcanic rock. Its unique structure consists of numerous concentric layers, similar to the layers in an onion. Its natural color ranges from light pearl gray to dark gray. The distinguishing feature which sets perlite apart from other volcanic siliceous rocks is that when heated above 1600°F, it expands up to 20 times its original size. The expansion is due to the presence of water (nearly 5%) trapped in the crude ore.

Perlite is used as filteraid in many chemicals filtration processes. It’s available in a full range of grades with specific permeabilities which produce varying degrees of clarification. The products are functionally similar to diatomaceous earth (DE) filter aids; however, they typically have bulk densities about half that of DE. Perlite is used to filter juices, waste water, beverages and industrial chemicals. They are produced from inert silicate minerals and meet the purity requirements of many applications, except those requiring the highest degree of clarification (such as polishing).
