Application:
HMDTMPA is a white crystal powder at room temperature, slightly soluble in water, with solubility less than 5%.
HMDTMPA can inhibit most scale formation such as calcium carbonate, calcium sulfate, barium sulfate and ferric oxide. As water treatment chemicals, HMDTMPAis used as scale inhibitors for calcium sulfate and barium sulfate, for calcium sulfate in particular. It has high scale inhibition rate and can last for long effective time. HMDTMPA can be used for crush treatment in oilfield and for water treatment in boiler.
Package and Storage:
25Kg/bag or customers' requirement. Storage for twelve month in shady room and dry place.
