Sodium carboxymethyl celluose(CMC-Na)is a anion type linear macromole substances. Features of pure substance: white or ivory, insipidity ,innocuity, fluidity, fibrous powder, freely soluble in cold or hot water to form transparent sticky solution, unique function. It is a very popular chemical and used in many industry, such as Food, Cosmetics, Ceramics, Oil drilling, Paint, Textile and dyeing, Paper and so on.
Used as additive in food field, CMC has the functions of thickening, suspending, emulsifying, stabilizing, shaping, filming, bulking, anti-corrosion, retaining freshness, acid-resisting, health protecting, etc. It can replace the application of guar gum, gelatin, agar, sodium alginate, and pectin. It is widely used in modern food industry, such as frozen food, solid drink, fruit juice, jam, lactic acid drinks, condiment, biscuit, instant noodles, bakery products, meat products, etc.
Our food grade CMC has good thickening property, water retention, dispersion stability, filming and chemical stability. It has high viscosity even in low concentration, and makes the food taste delicate and smooth; it can reduce the syneresis of food and extend the shelf life; it can control the crystal size in frozen food and prevent the stratification between oil and water; In acid system, our anti-acid products have good suspending stability, so it can improve the stability of milk and the impedance ability of protein; our CMC can be used together with other stabilizers and emulsifiers to complement each other, strengthen each other's effect and reduce the cost.

Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
