 Polymaleic Acid CAS#26099-09-2 Polymaleic acid is the homopolymer of maleic acid. It is very secure in presence of chlorine and different oxidizing biocides. It has correct scale inhibition and excessive temperature resistance properties. Therefore, it can be used in the water desalination plants. It is also an amazing calcium carbonate antiscalant upon excessive temperature and in the excessive alkaline cooling water systems.

Products Description of Di-tert-butyl Dicarbonate CAS#24424-99-5BOC anhydride is an organic compound with the molecular formula C10H18O5.

Products Description of Boric acid CAS#11113-50-1Boric acid is also called "orthoboric acid". It is derived from the interaction between natural borax (sodium borate) and acid. Soluble in water, ethanol and glycerin. The aqueous solution is acidic and is a monovalent weak acid. Solubility in water increases with temperature. Heated to 169℃ (±1℃), dehydration will produce metaboric acid, and 300℃ will form boric anhydride. Neutralize with strong base to obtain metaborate.
