A special milling and Classification process gives our perlite filter aids the structure and correct particle size range distribution needed for optimum performance. Perlite is an amorphous mineral consisting of fused sodium potassium aluminum silicate. Our perlite filter aids are processed at temperatures exceeding 800 Degree Celsius which eliminates organic matter. They have extremely low solubilities in mineral and organic acids at both low and high temperature.

Solubility in strong alkalis will vary according to temperature and time of contact. Our perlite filter aids do not impart taste or odor to liquids being filtered.

Due to their unique physical structure, perlite filter aids offer high flow rates with optimum clarity. They are especially applicable to highly viscous liquids such as syrup or gelatinous slurries requiring fast flow rates. Productivity, clarity and flow rates may be increased through the use of perlite filter aids. Because they remain porous and do not compact, perlite filter aids afford easy cake release.
