Aqoat Aqoat AS-HF/HG Aqoat AS-LP/LG-, Aqoat AS-MF/ MG cellulose, 2-hydroxypropyl methyl ether, acetate succinate HPMCAS. 

Cellulose esters or ethers such as methylcellulose (MC), ethylcellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropyl methylcellulose/hypromellose (HPMC), hypromeUose phthalate (HPMCP), hypromellose acetate phthalate (HPMCAP), hypromellose acetate succinate (HPMCAS), cellulose acetate (CA) and derivates Poly (methyl) methacrylates (Eudragit L, S, E, RS/ RL)... 

Since the hydroxyl groups in cellulose are reactive and can be easily functionalized, cellulose has been made into a large number of derivatives in the form of ethers, esters, and acetals, such as methyl cellulose, hydroxypropylcellulose, hydroxypropyl methyl cellulose, and carboxymethyl cellulose. These cellulose derivatives are soluble in a variety of solvents and can be easily processed into various forms, such as... 

Cellulose ethers, more particularly methyl cellulose (MQ, methylhydroxypro-pyl cellulose (MHPC) and hydroxypropyl cellulose (HPC) are used as protective colloids also called primary suspending agents in suspension polymerization for the manufacturing of S-PVC. Their role is maintaining the particle size of the resin. Hydroxyethyl cellulose (HEC) is preferred for manufacturing of vinyl acetate emulsion polymers and as a thickening agent in dispersimi paints.
