Sodium tripolyphosphate (STPP) FOOD GRADE
STPP FOR FISH INDUSTRY. DENSITY REQUEST: The density we are looking for, which is that of our reference products, is around 0.5-0.65 g / cm3. ?Regarding the particle size, the optimal distribution for us would be one in which about 90% of the product is greater than 70-75 microns, and 30-40% is above 200 microns. The percentages are cumulative, and not referred to each particle size segment. It is not that 90% has to be greater than 70-75 microns but less than 200 microns. I explain myself: a particle with a size greater than 200 microns will therefore be greater than 70 microns. That is, within 90% of particles greater than 70-75 microns, there is 30-40% that should be in turn greater than 200 microns.
