HEDPA with other corrosion and scale inhibitors, such as chromate, polymerization phosphate and molybdate, silicate, zinc salt, salt poly hydroxy acid and its derivatives, etc, has a synergistic effect, can improve the efficacy.

Because of the different raw materials, so HEDPA synthesis method is different also, so can be divided into three kinds: with phosphorus trichloride and Acetic acid as raw materials, with phosphorous acid and acetic anhydride as raw materials, phosphorous acid and acetyl chloride as the raw material.

1-Hydroxyethylidene-1,1-diphosphonic acid liquid packed in plastic drum, 30 kg or 250 kg a barrel; HEDP solid packed in plastic woven bags lined with polythene bags, bags of 25 kg net each, can also according to user’s need to make sure.
