APS product line composes of three types of products SCALE INHIBITORS, SCALE DISPERSANTS and SCALE REMOVAL Polycarboxylates:

In general, the Polycaboxylates rarely provide optimum performance against calcium carbonate. Some polymer inhibitors, particularly the higher molecular weight acrylate base products are sensitive to soluble calcium, which in sufficient concentration can precipitate the product as a calcium salt. On the other hand, this type of chemistry has proven itself on barium sulphate inhibition. Phosphorous-containing compounds: There are numerous combinations and different chemistry on the phosphorous group generally have good overall treatment – they are effective against most scale formations. As mentioned above in some cases the polycarboxylate groups are suited and perform better in certain circumstances.
