Hydroxypropyl Methyl Celluloes (HPMC)

Hydroxypropyl Methyl Celluloes (HPMC)
Product Detailed
Hydroxypropyl Methyl Celluloes (HPMC) 1.non-anioc surfactant 2.PH stability 3.good wettability,emulsification

Hydroxypropyl Methyl Celluloes (HPMC) 

Synonyms: 2-hydroxypropyl methyl ether Cellulose;

1.Product properties

1).Appearance : It is white or off-white crystalline powder,odorless,non-poisonous,tasteless.

2).Water solubility & thickening ability: It is a water souluble ether,with thermal gelation properties,which has excellent cold-water soluble and hot water insoluble properties, and form transparent and viscous solution.

3).Solubility in organic solvents: It is soluble in some of the organic solvents as well as in the mixture of water and some organic solvents. 4).Salt resistance: It is fairly stable in metal salts or organic electrolyte water solution5).Surface activity: Its water solution is surface active, thus it has emulsifying ability and is relatively stable, it also can be used as the protection colloid.6).Low ash content: It is non-ionic and has very low ash content.7).Water retention property: It has excellent water retention performance. 8).Film-forming property: It has good toughness,flexibility,can form transparent film which is solid, pliant, having good ability of resisting oil and grease,

9).PH stability:It has PH stability, strong enzyme resistance and metabolic inertia,the viscosity of its water solution is stable when PH is 3.0—11.0. 10).It has a good wettability, dispersion, emulsification, thickening, adhesiveness, water-retention and film formation,and impermeability for oil grease.
