* Applications:
HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330. HPMA has obvious threshold effect under high temperature (350) and high pH(8. 3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300 with effective time as long as 100 hours. HPMA can also used as additives for cement.
* Usage: It is mainly used in Cooling Water Treatment, Boilers, evaporators, RO membranes, secondary oil recovery. HPMA has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.
* Packing and storage:
Normally In 25kg or 200kg net Plastic Drum, IBC's can also be used as required. Stored in cool and dry place in one year.
