HPMC FOR GYPSUM,hpmc,cellulose ethers,hpmc manufacturer


Hydroxy propyl methyl cellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel. In the course of construction,HPMC is used for wall putty, tile adhesive, cement mortar, dry mix mortar, wall plaster, skim coat, mortar, concrete admixtures, cement, gypsum plaster, joints fillers, crack filler, etc.
Hydroxypropyl methyl cellulose (HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. they are an odorless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. 
It has the characteristics of thickening,bonding,dispersing,emulsifying, filmforming,suspension,adsorption,gelation,
surface activity, moisture retention and protective colloid.
1. Water-soluble, non-ionic cellulose  ether
2. Odorless, tasteless, non-toxic, white or off-white powder
3. Dissolved in cold water, forming a clear or slightly solution
4. Properties of thickening, binding, dispersing, emulsifying, film-forming, suspension, adsorption, gel, surface activity, water retention and protective colloid. 
This HPMC Industry Grade Cellulose Ether has been tested strictly. 
In construction Mortar, the dosage of HPMC is very low, an important additive in construction, play the role of water retention, thickener, workability in construction mortar.

Gypsum is a kind of building material that will form a large number of micropores in the material after curing, and its porosity makes the wall has a breathing function and absorption,insulation effect, this breathing function can regulate the humidity of the living and working environment and create a comfortable microclimate, making gypsum play an increasingly important role in modern interior decoration.
HPMC is essential in gypsum-based products, whether in gypsum-based leveling mortars, grout compound, putty or gypsum-based self-leveling; it has certain set-retarding effects on gypsum-based products.
HPMC is not sensitive to the alkalinity of gypsum, it can be quickly infiltrated in all kinds of gypsum products without agglomeration, and has no negative influence on the porosity of cured gypsum products, so as to ensure the breathing performance of gypsum products; with appropriate wet adhesion to ensure the bonding ability of the material to the substrate, which greatly improves the construction performance of gypsum products, and is easy to spread without sticking to tools.
HPMC offers the following advantages to gypsum plaster:
1. Improve the uniformity, make the plaster easier to coat,
2. Improve the anti-sagging ability to enhance the fluidity and pump ability and improve work efficiency.
3. High water retention, extend the working time of the mortar, and produce high mechanical strength during solidification.
4. By controlling the consistency of the mortar, a high-quality surface coating is formed. 
Which is a specialized enterprise on researching, developing, producing and promoting of hydroxypropyl methyl cellulose (HPMC)--Other name Hypromellose. It one of the largest HPMC manufacturer in North of china ,we has successfully passed the most authentications of ISO 9001:2000 certificate. our factory is more than 10 years history in HPMC.
we total investment 15 million USD and cover land of more than 30,000 square meters, more than 200 employees and It includes 10 high level technical engineers in the factory.
