[CAS] 26099-09-02 Dequest : P9000
1,Properties :
HPMA is a low molecular weight polymeride . with average molecular weight 400-800 . No toxicity , soluble in water , high chemical and thermal stability , dicomposed 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 phosphoate scales under temperature 300℃ with effective time as long as 100 hours . Due to its good scale inhibitiong and high temperature tolerance properties , HPMA is widely used in desalination plant of flash vaporization equipment . low pressure boilwe , steam locomotive , crude oil evaporation , petroleum pipeline , and industrial circulating cool water systems . In addition , HPMA has good corrosion inhibition effect when used together with zinc salt . HPMA can also used as additives for cement .
