Hydroxypropyl methyl cellulose

Superiority:

Methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials -- cellulose as raw material, and through a series of chemical processing of nonionic cellulose ether. Methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC) is a non self color powder smell, tasteless, non-toxic, can be dissolved in water, forming a transparent viscous solution, with thickening, adhesion, dispersion, emulsion, film forming, suspension, adsorption, coagulation, surface activity, keep moisture and protective colloid properties.
Methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) can be applied to building materials, paint, synthetic resin, ceramics, medicine, food, textile, agriculture, cosmetics and tobacco industry.
Product specifications and classification of products is divided into cold water soluble S and ordinary type

2. The nature of the product
 
Properties: the product is a white or off white powder, odorless, tasteless, non-toxic.
 
And thickening ability of water: This product can dissolve in water, forming a transparent viscous solution.
 
Soluble in organic solvents: due to the hydrophobic methoxy contains a certain amount of, this product can dissolve in some organic solvent, can dissolve in water and organic mixed solvent.
 
Salt resistance: because this product is non ion type polymer, therefore, it in the aqueous solution of metal salt or organic electrolyte is stable.
 
The surface activity in aqueous solution: This product has the surface activity, emulsifying, protective colloid and relative stability and performance.
 
Thermal gelation: This product is water solution is heated to a certain temperature becomes opaque, until the formation of (poly) flocculation condition, the solution loses stickiness. But in the cooling and will change into the original solution. Types, solution gel phenomenon of temperature depends on the product of concentration and heating rate.
 
PH stability: the product water solution viscosity in the range of PH3.0-11.0 stability.
 
Effect of water retention: because this product is hydrophilic, added to the mortar, plaster, paint, maintain the role of Gao Baoshui in.
 
Shape: compared with other water-soluble polymers, the product of the aqueous solution with the viscoelastic properties of special. It joined the ability to maintain extruded ceramic products shape etc..
 
Lubrication: This product can reduce the friction coefficient and improve the lubrication of extruded ceramic products and cement products.
 
Film: This product can produce flexible, transparent, excellent mechanical properties of thin film, with good oil resistant grease
