Hydroxypropyl methylcellulose (HPMC) is a kind of non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer. It is widely used in construction, food, cosmetics and personal care products, medicine, and other industries. HPMC polymers for fabricating hydrophilic matrix systems are available in various viscosity grades ranging from 4000–100,000 mPa s.

Carboxymethyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable performance and easily soluble in water. Its aqueous solution is neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, insoluble Used in organic solvents such as ethanol. CMC can be used as binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.

PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment.
