Carboxymethyl cellulose (CMC)
Product Description
Carboxymethyl cellulose (CMC) is a common polymer compound with many outstanding properties and applications. The following are some of the main characteristics and applications of CMC.
Properties:
CMC is a colorless, tasteless, odorless, water-soluble powder compound.
It has excellent stability and viscosity and is capable of forming strong colloidal solutions.
CMC also has surfactant properties and therefore has good lubricity and dispersibility.
CMC’s water solubility and ion exchange ability make it an excellent adsorbent and dehydrating agent.
Applications:
CMC is mainly used as thickener, emulsifier, stabilizer, binder and dispersant in food, pharmaceutical, pulp and textile industries.
CMC is also used in the petroleum, cosmetic, coating, ceramic and construction material industries.
Parameters:
The properties of CMC depend on factors such as its viscosity, representative viscosity (DP) and degree of carboxymethyl substitution (DS).
The viscosity of CMC usually ranges from 500-5000 mPa.s, DP usually ranges from 300-1200 and DS usually ranges from 0.5-1.5.
