HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
Packing : 25 KG per woven bag made with compound woven fabric and inner PE bag.
- 15000kg (600 bags) of palletized goods in 20' container.
- 24000kg (960 bags) of palletized goods in 40' container.
1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks, which can enhance the strength of the cement.
2. Tile cement: improve the plasticity, water retention of the pressed tile mortar, improve the bonding strength of the tile, prevent powdering.
3. Gypsum coagulation slurry: Improves water retention and processability, and improves the adhesion to the substrate.
4. Seam cement: added to the joint cement for gypsum board to improve fluidity and water retention.
5. Coatings: As a plasticizer for latex coatings, it has an effect on improving the handling properties and fluidity of coatings and putty powder.
Advantages:
Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent.
Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exsist in this product, its metal salt or organic electrolyte aqueous solution is stable.
Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability.
Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low.
pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable.
Water retention effect: this product is hydrophilic and its solution has high viscosity.
Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance.
