Product details & specifications
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.
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.
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.
