Currently on the market many kinds of thickeners can be used , there are inorganic thickeners , cellulose , polyacrylates , and four associative polyurethane thickener . Many cellulosic thickener long history of use , variety, methyl cellulose , carboxymethyl cellulose , hydroxyethyl cellulose , hydroxypropyl methyl cellulose , was the main thickener the most commonly used is hydroxyethylcellulose. Polyacrylate thickener can be essentially divided into two types : one is a water-soluble polyacrylates ; another are acrylic acid, methacrylic acid homopolymer or copolymer emulsion thickeners, such thickeners itself is acidic , alkali or ammonia required to pH8 ~ 9 and the thickening effect can be achieved , also known as acrylic alkali swellable thickener. Polyurethane thickeners are newly developed associative thickener . Is a kind of inorganic thickeners swelling thixotropic gel formed minerals. There are bentonite, attapulgite , aluminum silicate , bentonite, which is most commonly used .
 Thickeners actually used by the mechanism can be divided into the aqueous phase and oil phase thickener thickener two categories , the former a lot of variety , which is very small.
 The following are some thickener categories:
 ( 1 ) inorganic thickeners ( fumed silica , sodium bentonite , organic bentonite , diatomaceous earth, attapulgite clay, zeolite , silica gel ) .
 ( 2 ) Cellulose ether ( methyl cellulose , hydroxypropyl methyl cellulose, sodium carboxymethyl cellulose , hydroxyethyl cellulose ) .
 ( 3 ) a natural polymer and their derivatives ( starch , gelatin , sodium alginate , casein , guar gum , chitosan , gum arabic , xanthan gum , soy protein glue , natural rubber, lanolin , agar ) .
 ( 4 ) Synthesis of polymer ( polyacrylamide, polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene oxide , modified paraffin resins, Carbopol resins , polyacrylic acid , polyacrylic ester copolymer emulsion , butadiene rubber , styrene butadiene rubber , urethane , polyurea modified , low molecular weight polyethylene wax ) .
 ( 5 ) organic metal complex compound ( amino alcohol complexing titanate ) .
 ( 6 ) Printing thickeners include ( dispersion paint thickener thickener active thickener )
