BassTech International supplies Fabutit 734 produced by Chemische Fabrik Budenheim. Fabutit 734, owing to its special composition, is a very effective deflocculant. Compared to common Sodium Tripolyphosphate (STPP), it particularly excels in solubility and efficiency. High solids contents can be obtained even with products considered difficult to liquefy. In a standard test with a 70% clay suspension, Fabutit 734 is about three times more effective when compared to standard STPP.
The most favorable addition ratio is between 0.1 and 0.5% by weight, based on the solids content. Since the effect on different raw material can vary, we suggest carrying out comparative tests.
The following diagram is a comparison between Fabutit 734 and common STPP. The deflocculating effect of Fabutit 734 is remarkably better than with STPP. The test was made with a 70% suspension of clay. The addition ratio varies between 0.2 and 0.6%. The viscosity was measured in mPas by a Brookfield-viscometer.

What is STPP?
Sodium Tripolyphosphate is an inorganic compound with the formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Our Fabutit 734 is a proprietary modification of STPP allowing for better deflocculation at a lower addition ratio.
