Methylcellulose Ceramic Binder & Plasticizer
CAS Number: 9004-67-5
Methylcellulose (MC) is a non-ionic cellulose ether used as a binder, plasticizer, and rheology modifier in ceramic extrusion and injection molding. Its unique thermal gelation property—forming a gel when heated—provides shape retention during extrusion of honeycomb bodies, catalytic substrates, and tubes. It burns out cleanly during sintering.
