Hydroxypropyl Methyl Cellulose
Hydroxypropyl methyl cellulose, also known as hydroxypropyl cellulose and cellulose hydroxypropyl methyl ether, is made of high-purity cotton cellulose as raw material and specially etherified under alkaline conditions.
(1) Main purpose:
① Polyvinyl chloride: used as a dispersant in the production of polyvinyl chloride, and the main auxiliary agent for the preparation of polyvinyl chloride by suspension polymerization.
②Construction industry: As a water-retaining agent and retarder of cement mortar, the mortar can be pumped. Used as a binder for plaster, plaster, putty powder or other building materials to improve dispersibility and extend the use time. It can be used as a strengthening agent for tile, marble, plastic decoration, and sticking, and can reduce the amount of cement. The water retention properties of HPMC prevent the slurry from cracking due to excessive drying after application, and improve the strength of the slurry after hardening.
③Ceramic manufacturing industry: widely used as a binder for ceramic products.
④Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. Used as paint remover.
⑤Ink printing: As thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
⑥ Plastic: used as a release agent, softener, lubricant, etc.
⑦Pharmaceutical industry: coating materials, film materials, controlled-release polymer materials, stabilizers, suspending agents, tablet adhesives and tackifiers for sustained-release preparations.
⑧Others: This product is also widely used in leather, paper products, fruit and vegetable preservation, textiles and other industries.
