Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation.

HPS is a kind of ionic hydroxypropyl starch ether, which is produced by a series of chemical and physical reactions with starch as raw material. It is a kind of non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid.

Main applicationHPMC is one of the main dispersants in PVC industry. During suspension polymerization of vinyl chloride, it can reduce the interfacial tension between vinyl chloride monomer (VCM) and water, and help VCM to be evenly and stably dispersed in the aqueous medium; Prevent the coalescence of VCM droplets at the initial stage of polymerization; Prevent coalescence between polymer particles in the later stage of the polymerization process. In suspension polymerization system, it plays a dual role of dispersion and stability protection.

HPMC is mainly used in the field of honeycomb ceramics. Honeycomb ceramics were first used to purify the exhaust gas of small cars. Now they have been widely used in chemical industry, electric power metallurgy, petroleum, electronics, electrical appliances, machinery and other industries. With the development of technology, more and more thin～walled honeycomb ceramics are used.

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose mixed ether made from cotton and wood through alkalization, propylene oxide and methyl chloride etherification.

Self leveling mortar includes cement～based self leveling mortar, self leveling mortar, leveling mortar, etc. it is a dry mixed powder material composed of a variety of active ingredients, which can be used by mixing water on site. The high leveled base surface can be obtained after being slightly expanded by the scraper.

ETON HPMC can make the honeycomb ceramic product have a very dense internal structure after combustion.The addition of ETON HPMC in the honeycomb ceramic has an obvious effect on the shape preservation of the green tire, which can ensure the dimensional accuracy of the product, ensure the uniformity of the wall thickness, and reduce the rejection rate.Specification           TypeItemHPMCMethoxy %28.0～30.0Hydroxypropyl %7.0～12.0Gel temperature ℃58.0～64.0Viscosity mPa.s4000,6000,8000,10000pH5.5～8.0Loss on drying %≤4.

Cellulose water-retaining agentAt present, the most widely used in the market is hydroxypropyl methyl cellulose, followed by methyl cellulose, and then carboxymethyl cellulose. The comprehensive performance of hydroxypropyl methyl cellulose is better than that of methyl cellulose, and the water retention of the two is much higher than that of carboxymethyl cellulose, but the thickening effect and bonding effect are worse than that of carboxymethyl cellulose.
