quality
It is an important variety in non-ionic cellulose mixed ethers. Odorless, tasteless and non-toxic, its finished product is white powder or loose fiber, and the particle size passes through an 80 mesh sieve. It does not react with heavy metals. The proportion of methoxy content and hydroxypropyl content in the finished product is different, and the viscosity is different, so it becomes a variety with different properties. HPMC is actually a methyl cellulose modified by methane (methyloxypropylene ring), so it has the characteristics of methyl cellulose similar to soluble in cold water and insoluble in hot water, and its solubility in organic solvents is better than that of water, it can be soluble in anhydrous methanol and ethanol, and can also be dissolved in chlorinated hydrocarbons such as dichloromethane, trichloroethane and organic solvents such as acetone, isopropanol, and diacetone alcohol.
use
In the polymerization reaction of synthetic resins, HPMC can be used as a dispersant and suspension agent for the polymerization reaction of vinyl chloride and its copolymers; Emulsifier for dichloroethylene vinyl acetate copolymer; Suspension stabilizer for vinyl acetate and vinyl chloride copolymer; Stabilizer for butadiene, acrylonitrile, styrene graft copolymerization, etc. As an additive in the pharmaceutical and food industry, it has the effects of thickening, solidifying, film-forming, dispersing, and stabilizing, as well as preventing moisture, mildew, and retaining moisture. In the coating industry, it can be used as an emulsifier, thickener, film-forming agent and stabilizer, and in photosensitive printing and board making, it mainly uses its film-forming and photodegradability, and it can be quickly developed with water. As a detergent, it can improve the stain resistance of fabrics.
