Product Notes

sodium trimetaphosphate (“STMP”) can be utilized in the wallboard manufacturing process to increase the quality of wallboard. But note STMP is ineffective in high pH level environments (i.e., greater than 10). In all other environments, STMP can be used to increase the core quality of wallboard and allow manufacturers to reduce the amount of natural polymer (i.e., starch) used to produce wallboard of suitable quality. 

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.

STMP is a combination of earth metals and is known by the chemical equation (NaPO3)3. In its solid form it is a salt, but when dissolved in an aqueous solution, it is present as a trimetaphosphate ion.
