How is STPP Used in Ceramic Sector?

Sodium Tri Polyphosphate (STPP) is generally employed as a dispersing agent in ceramic processing and could be a low-cost plasticizer for ceramic based materials. The effect was inverted in the case of higher STPP concentrations, for which faster setting of ceramic product can be observed.

What are the Applications of STPP in others?

In household cleaning products, sodium tri polyphosphate is used most widely as builder. In conjunction with surfactants, it allows detergents to perform efficiently in all washing conditions. It is widely used in laundry detergents, dishwasher detergents, industrial and institutional detergents
