Sodium Trimetaphosphate (STMP)  is a Sodium Phosphate salt (NaPO3)3, supplier and exporter. Sodium Trimetaphosphate, Anhydrous (STMP) Powder is a clean, white powder. Sodium Trimetaphosphate. Applications include food processing, starch modification, pharmaceuticals, and potable water treatment.

Application

Sodium Trimetaphosphate (STMP)  is a Sodium Phosphate salt (NaPO3)3, that when added to gypsum can help to optimize the setting time while enhancing the structural integrity of the wallboard.  STMP is an important additive in the production of high throughput and high quality wallboard for use by businesses and individuals in the construction and home remodeling industry.

Technical Specification

It is believed that the addition of STMP to the slurry promotes long crystal growth. Such crystals add the most strength to the core of the wallboard and also serve to form stronger bonds between the core and paper. While in theory, STMP can be used by manufacturers to decrease costs by increasing the core quality of wallboard, it has been discovered in practice that the current methods of adding STMP leads to further problems and delays.
