The raw material of hydroxypropyl methylcellulose is refined cotton. There is no harm to the human body, close contact with the nose will be a little sticky, but will not enter the lungs, if you work in the factory or recommended to bring a good mask.
Hydroxypropyl methyl cellulose is a naturally occurring cellulose ether, non-toxic, cellulose using naturally occurring fibers after alkali soluble, catching technology reaction, washing, drying, grinding and other processes. We can rest assured that it will not jeopardize human health.
Hydroxypropyl methyl cellulose for industrial grade HPMC, the main use of polyvinyl chloride production as a dispersant, the Department of suspension polymerization to prepare the main agent of PVC. In addition, it is used as thickener, stabilizer, emulsifier, excipient, water retention agent, film-forming agent in other petrochemicals, coatings, building materials, paint remover, agrochemicals, inks, textile printing and dyeing, ceramics, paper making, cosmetics and other products.
In the application of synthetic resin, it can make the obtained products have the characteristics of regular particles, loose, appropriate specific gravity and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersant.
