Lignin

Name:
Lignin
Detailed information:
A phenylpropane polymer of amorphous structure comprising 17–30% wood. It is so closely associated with the holocellulose which makes up the balance of woody material that it can be separated from it only by chemical reaction at high temperature. It is believed to function as a plastic binder for the holocellulose fibers. It is recovered from wood-processing wastes in limited amounts.

Use:

Stabilization of asphalt emulsions, ceramic binder and deflocculant, dye leveler and dispersant, drilling-fluid additive, precipitation of proteins, extender for phenolic plastics, special molded products, source of vanillin, phenol, and of a component of battery expanders.
