Properties:

MC is a kind of non-ion aqueous cellulous ether,white or white-similar powder or granule,no odor or taste,nontoxic,with a little hygroscopicity. Different substitution offers different solubility,usually medium substitution(DS between 1.5-2.0) comes under cool aqueous model,and finds widest applications.It dissolves in cool water and some organic solvents,does not dissolve in hot water.In hot water at 80-90°C it dissolves and swells,after cooled down,dissolving quick.Its solution possesses reversible hot gelling characteristic,stable to acid and alkali,is not effected between PH 2-12, with excellent anti-mildew ability,capable of dispersing, emulsifying, agglomerating, thickening, holding water,forming film etc.Film formed by its offers superior toughness flexibility, transparency and oil resistance.

Specification:

Usage:

The product is used as agents of thickening,coherence,water-holding,film-forming, shaping, dispersing, retard etc.In building construction, building material, coating, ceramics, textile printing & dyeing,leather,tobacco, ink,paper making,petrochemical,daily-use chemical etc.For example,putting MC in cement slurry may decrease water loss on the surface, even if used in dry wall it also can prevent wall cracking, improve its coherence and workability;used in cement product, MC makes it firm and hard but not shrink too much; used in emulsion or aqueous resin coating, MC gives coating a good wearability,fluidity,uniformity,stability for storage and endurance to heavy metal pigment dissolving.
In pharmaceutical and food industries MC is used as agent of coherence,film forming, emulsification

 and suspension etc.
