aqualon™ and blanose™ carboxymethylcellulose (CMC)
chemistry: cellulosics
Carboxymethyl cellulose products are e.g. widely used in ceramic glazes. Here, specifically low molecular weight products are being used to prevent or reduce sedimentation, have a low impact on the glaze viscosity and support adhesion of the glaze on the ceramic substrate. Low molecular weight carboxymethyl cellulose is also widely used for die pressing applications, where it is incorporated as a binder during the spray drying process of the ceramic slip. Other uses are in slip- or tape casting applications.
Application for higher molecular weight, and often fine particle sized, products would be ceramic extrusion and extrusion of non-ceramic materials such as activated carbon for fuel recovery systems.
Aqualon™ and Blanose™ products are available in:
- various substitution levels, depending on end application needs
- low to very high molecular weight
- very fine to coarse particle size
- different purity levels (98%, 99.5%)
