It called hydroxypropyl methyl cellulose,hydroxypropyl methyl cellulose ether,is highly pure cotton cellulose as raw materials,under the condition of alkaline specially made by etherification.
2. The main purpose
1). The construction industry as cement mortar water retention agent,retarder,make the slurry pump.In plaster
mortar,gypsum material,putty powder or other materials as a binder,improve the workability and extend the operational time.Used as the adornment,stickup ceramic tile, marble, plastic paste enhancer, can also reduce the dosage of cement.Water retention properties of HPMC to paste in the daub after will not crack by dry too fast, enhance strength after hardening.
2). Ceramic manufacturing: widely used as binder in the ceramic product manufacture.
3). Due to:in due as a thickening agent, dispersing agent and stabilizer,in water or organic solvents have good intermiscibility.As the paint remover.
4). The printing ink: in printing ink industry as a thickening agent, dispersing agent and stabilizer, in water or organic solvents have good intermiscibility.
5). Plastic: as forming mold release agent, softener, lubricants, etc.
6). Polyvinyl chloride (PVC) :do dispersing agent in the production of PVC, PVC suspension polymerization preparation main auxiliaries.
7). Other: this product is widely used in leather, paper products, fresh-keeping and textile industry etc.
