Physical and chemical properties of cellulose (HPMC)

1. Properties: MC is almost insoluble in anhydrous ethanol and acetone.It quickly disperses and swells in hot water at 80~90ºC and dissolves quickly after cooling. The aqueous solution is quite stable at room temperature and can gel at high temperature, and the gel can change with the temperature of the solution.It has excellent wettability, dispersability, adhesion, thickening, emulsification, water retention and film formation, as well as the impermeability of oil.The film has excellent toughness, flexibility and transparency. Because it is non-ionic, it can be compatible with other emulsifiers, but it is easy to salt-out, and the solution is stable in the range of pH2-12.

2. Apparent density: 0.30-0.70g/cm3, density is about 1.3g/cm3.
3. Appearance: MC is white or almost white fibrous or granular powder, odorless.

Hydroxypropyl methyl cellulose (HPMC) is widely used in construction, building materials, dispersive coatings, wallpaper paste, polymerization additives, in addition to paint, leather, printing ink, paper, etc., respectively used as a thickening agent, adhesive, water retention agent, film forming agent, excipient.If used as an adhesive, thickening agent and water-retaining agent in building materials, used as a film forming agent and thickening agent in the coating industry, in addition to oil drilling and daily chemical industry and other fields are also more widely used.
HPMC is odorless, tasteless, non-toxic cellulose ethers produced from natural high molecular cellulose through series of chemical processing and achieved. It is a white color powder with good water solubility. It has thickening, adhesion, dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties, etc.
HEMCHydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose ether made from natural polymer material cellulose after a series of etherification. It is an odorless, tasteless, non-toxic white powder Or particles, soluble in cold and hot water to form a transparent viscous solution, insoluble in general organic solvents, and the dissolution is not affected by the pH value. It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, surface activity, moisture retention, and salt resistance.HECHydroxyethyl Cellulose (HEC) has two components: one is cellulose, and the other is a hydroxyethyl branched chain. Yida hydroxyethyl cellulose is purified by the reaction of cellulose and sodium hydroxide, the formation of alkaline fiber colloid, adding ethylene oxide in the colloid production, after the modification of production. Yida hydroxyethyl cellulose can be thickened, bonded, dispersed, stable and other functions, and can retain water, form a film, and provide protective colloid.
