Qemi International's slogan
polymer applications

polymersWe offer a complete range of water soluble polymer PAM (polyacrylamide) based flocculants and coagulants including polyamines and polydadmacs designed to cover all types of water solids separation processes and specialty applications such as clarification, thickening, flotation, filtration, settling, etc. They are available in emulsion, dry and liquid forms; cationic, anionic and non-ionic charges; and in the broadest range of molecular weights and charge densities.  Note: see Polymer Preparation guidelines and equipment.

A list of common industries and applications are shown below.  Please contact us with your specific polymer requirements.
