Diatomaceous Earth Lightweight Fillers

In today’s complex world of formulations, diatomaceous earth lightweight fillers have reached economic importance because they offer distinct property advantages and are cost effective.

The traditional role of these functional fillers as bulking agents and extenders for cost reduction at the expense of performance has given way to the highly technical design of desired properties for specific product applications.

As product applications and uses become more sophisticated and functional fillers take on a more prominent role, the trend is toward mixtures of fillers and binders that yield desired properties at the lowest cost.

Our Mineral Fillers are Used in a Wide Range of Products and Applications

  • Absorbent

Diatomite occupies up to 30% more volume per-pound than most competing minerals. This advantage is critical in those applications requiring light weighting.

Why Dicalite?

We are one of only a few companies in the world that manufacture a complete line of diatomite functional fillers. Our lightweight fillers are grouped into three categories based on the nature of the processing. Products in these groups are classified according to color, surface area, hardness, and particle characteristics. The effective density of Dicalite diatomite fillers is 1.98 to 2.33 gm/cc—among the lowest of any mineral filler!
