PHENOLIC MOLDING COMPOUNDS (Panasonic)
Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid- or base-catalyzed. Hexamethylenetetramine or "hexamine" is a hardener added to crosslink novolac. Base-catalyzed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of greater than one, these resins are called resoles. PHENOL resin in pulp, wood flour such as fillers, coloring agents, denaturing agents are added to make the PHENOL MOLDING COMPOUND.
