DICALITE Diatomite functional fillers are produced from diatomaceous earth, a versatile and valuable raw material.
Diatomite is more than just a crystal or mineral that formed in a rock. It consists of delicately constructed silica skeletons grown by uncounted microscopic organisms each with its own design.
Deposits of these skeletons are collections of solid and perforated rods, disks, hemispheres, crescents and polygons. Because of their unusual physical structure the particles interlace and overlay in a random, three dimensional matrix which stiffens, reinforces, and improves the durability of filled systems.
The myriad of shapes also offers major advantages in terms of low density and high absorption. |
