Precipitated silica used for carrier

Features:TOND-255S is a fine particle silica with high oil absorption (DBP)and very good flow properties,it is a good caking inhibitor for powder too.

TOND-255HS is a fine particle silica with high absorption capacity for liqulids.It is a good thickener for liquids systerms.

Application range:Medicine, food, pesticides and feed additive industries.
