At present, there are many types of thickeners that can be used on the market, mainly including inorganic thickeners, celluloses, polyacrylates and associative polyurethane thickeners.

Inorganic thickeners are a class of thixotropic gel minerals that absorb water to swell. There are mainly bentonite, attapulgite, aluminum silicate, etc. Among them, bentonite is the most commonly used.

The use history and types of cellulose thickeners are many. There are methyl cellulose, cellulose sulfate, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, etc., which have been the mainstream of thickeners. Is hydroxyethyl cellulose.

There are basically two types of polyacrylate thickeners: one is a stepwise polyacrylate; the other is a homopolymer or copolymer emulsion thickener of acrylic acid or methacrylic acid. It is acidic and must be neutralized to pH 8 ~ 9 with alkali or ammonia water to achieve thickening effect. It is also called alkali carbonate swelling thickener.

Polyurethane thickener is a permanently newly developed associative thickener.
