5.Good hpmc/mhpc
Chemical hpmc advantage
1.Water soluble and thickening ability: this product can soluble in cold water, form transparent sticky solution.
In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, therefore, this product can soluble in some organic solvent, also can soluble in water and organic mixed solvent.
2.Hydroxypropyl methyl cellulose (HPMC) salt resistance: because in this product are ion and the polyelectrolyte, therefore, it is metal salt or organic electrolyte aqueous solution is stable.
3.Surface activity: HPMC for daily chemical aqueous solution has the surface activity, make its have emulsification, protective colloid and relative stability.
4.Low ash content: because in this product are ionic, in preparation process can use hot water washing effectively refined, so its ash content is very low.
5.PH stability: HPMC aqueous solution viscosity in PH3.0-11.0 range are more stable.
6.Water retention effect: because in this product is hydrophilic and its solution is of high viscosity. Film-7,forming property: HPMC can generate strong pliable, transparent sheet, has the good oil resistance to ester performance.
