Product Description

 

    Methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) is a kind of non-ionic cellulose ether which made from cellulose, by a series of chemical processing. MC and HPMC are odorless, tasteless, non-toxic white powder.  They can dissolve in cold waterand come into being transparent viscous solution, with features of thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gel, surface activity, protective colloid and keep water.

 

Methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) can be used in building materials, paint, synthetic resin, ceramics, pharmaceuticals, food, textile, agricultural, cosmetic and tobacco industry.

The product properties

Properties: this product is a white or kind of white powder. It is non-toxic, odorless and tasteless.

 

Water soluble and thickening ability:this product is soluble in cold water and come into being transparent viscous solution.

 

Dissolved in organic solvents:because of containing a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent, and it can be also dissolve in water and organic mixed solvents.

 

Salt resistance:because this product is non-ionic polymer, it is stable in metal salt or organic electrolyte aqueous solution.

 

Surface activity:the aqueous solution of this product has surface activity, it has function of emulsification, protective colloid and relatively stability.

 

Thermal gelation function:when the aqueous solution of the product heated to a certain temperature, it becomes opaque and turns into flocculation state with a bereft of viscosity. But after cooling, it will be transformed into the original solution state. The temperature of gel phenomenon depends on the type of product, the concentration of the solution and heating rate.

 

Low ash contentBecause of the thermal gelation, in the process of production,it can be refined by hot water washing the products.

 

PH stability:the viscosity of this product’s aqueous solution is stable in PH3.0-11.0.

 

Water retention: since this product is hydrophilic, it can be added to the mortar, plaster, paint, etc, to keep water effectively.

 

Shape preserving:compared with other water-soluble polymer, the product’s aqueous solution can have special viscoelastic. Its joining has the ability to keep the shape of the extruded ceramic products unchanged.

 

Lubricity:this product can reduce the friction coefficient and improve the lubricity of extruded ceramic products and cement products.

 

Film-forming: this product can turns into flexible, transparent and excellent mechanical properties thin films, it has good performance of resistance to oil and grease.

 

 

 Physicochemical property

Granularity:100 mesh passing rate is more than 98.5%, 80 mesh passing rate is 100%.

carbonization temperature: 280-300℃

apparent density: 0.25~0.70/cm   specific gravity:1.26-1.31

color-change temperature: 190~200℃

surface tension:42~56dyn/cm in 2% aqueous solution

solubility property: Soluble in water and some solvent, water solution has surface activity. High transparency and stable performance.  Solubility will be changed with viscosity, lower viscosity, more solubility.

 

 

Main application

 

 Industrial-grade HPMC mainly use as PVC dispersant, it is main additives of suspension polymerization of PVC. In addition, it also use as thickener, stabilizer, emulsifier, excipients, water retention agent, film former in the petroleum chemical industry, paint, building materials, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. In the application of synthetic resin, it can make the products neat, loose and have proper apparent specific gravity, and make the processing characteristics have a excellent performance. Therefore, it can instead of gelatin and pva as dispersant.
