Abstract

PURPOSE: To obtain the titled composition useful as a molding material having improved storage stability without causing bulk formation and occurrence of adhesion, by adding a precondensate of a novolak type phenolic resin to the reaction system of a resol type phenolic resin during the reaction.
CONSTITUTION: (A) A phenol is blended with (B) an aldehyde, e.g., formaldehyde etc. in a given molar ratio, and (C) preferably 5W30wt% based on component A of precondensate of a solid novolak type phenolic resin is added to the blend and the reaction is carried out in the presence of an alkali catalyst, to give a solid resol type phenolic resin. A release agent, e.g., stearic acid, etc. and a colorant, e.g., carbon black, etc. are added to the phenolic resin, which is ground to give a molding material.
USE: A general electrical insulating material free from ammonia, e.g., breaker, etc.
