PERLITE FUNCTIONAL FILLERS |
| DICALITE and DICAPERL Perlite functional fillers are a versatile
family of mineral-based silicate products available throughout the world.
These fillers are processed from amorphous, naturally-occurring glass found
where there has been volcanic activity. When processed under the proper
conditions the solid glass particles expand like popcorn up to 20 times
their original volume. A specialized process incorporating expansion,
selective milling and sizing determines the particle shape of each filler
product.
The variety of flake or di-, tri-, and tetrahedral particle shapes are obtained by this exclusive process. These unique shapes provide numerous functions including high surface area, permeability and reinforcement and have densities among the lowest of any of the mineral fillers. In addition to superior spatial loading, this property affords customers the added bonus of density control in their finished products. Dicalite Perlite fillers are inert to all but strong acids or alkalis and have no residual surface reactivity. After processing they are free of any organic contamination. Dicalite and Dicaperl Minerals, Inc. offers several grades of perlite functional fillers. All Dicalite and Dicaperl Perlite fillers are available with surface modification.
