This is our products list:
1.ATMP
is a phosphonate widely used in treating cooling or boiler water systems as scale and corrosion inhibitor. Many of water treatment chemical formulations contain ATMP as an important ingredient due to following advantages:Multifunctional performance from a single raw materialSuperior cost/performance in scale inhibitionSynergistic performance from formulated mixturesReplacement of sequestration levels of other chelantsWith threshold levels of phosphonate
Scale control for cooling water & boiler water treatmentScale & corrosion control for oilfield water treatmentBottle washing: prevent from scale, spotting and filmingTextile industries: stabilized peroxide, improve bleaching performance
