What have these "warriors' shields'' got to do with better product performance

?

A m o n g t h e h u n d r e d s of different types of par­ ticles found in Celite diatomaceous earth are these "warriors' shields." Shown here magnified hundreds of times, are, from left to right, Navicula splendida, Raphoneis arnphiceros and Navicula lyra.

They're particles of CELITE t h a t adds s t r e n g t h Celite's unique diatomite structurels shown in this photomicrograph. The infinite variety of particle shapes and sizes gives Celite its exceptional performance characteristics in a wide range of process applications.

CELITE

A d d s s t r e n g t h t o m o l d e d p l a s t i c s . T h e harder grades of Celite îxnpart high impact strength to many plastic products. Celite fillers also provide a more attractive surface finish and greater resistance to lieat a_nd moisture.

H e l p s p o l i s h - c l e a n e r s s o a k u p d i r t . Celite's highly porous diatomite structure soaks up and retains dirt and grease .. . provides easier "wipe-off" of polish-cleaners. This same structure gives these products a mild, non-scratching abrasive action.

C o n t r o l s gl o s s ΐ η p a i n t s . When included in paint formulations, irregular- Celite particles protrude through t h e surface, diffusing light a n d providing a highly desirable flat appearance. Celite's high oil absorption also provides viscosity- control for t h e finishes industry.

-the diatomite mineral filler soaks up dirt-controls gloss JLHE structure of the individual dia­ tom particle is the key to the success achieved by Celite* diatomite in so many process applications. It requires 40 million whole or frag­ mentary particles to form a cubic inch of crude Celite. Consequently, even when added in small proportions, their properties are greatly magnified and widely dispersed throughout a formulation. Relatively hard and irregularly shaped, particle contact is mainly lim­ ited to protruding outer points. There­ fore, Celite won't pack down and has

an extremely low apparent bulk: den­ sity of 10 lb/cu ft. T h i s explains Celite's high bulking action, excellent suspendability, and l a r g e particle surface area. This same limited particle contact means that 93% of a given volume of Celite is composed of air pockets or voids. And, since the particles 'theirLselves are porous and cellular in struc­ ture, Celite can absorb more than twice its weight of liquid before reach­ ing its limit. Celite is produced from t h e world's purest source of commercially avail­

able diatomaceous silica a t Lompoc, California. Celite comes in a wide range of grades . . . each carefully controlled for complete uniformity.
