摘要:
A phenolic resin molding compound, which is thermally stable in a heating cylinder, is provided. By using the phenolic resin molding compound, moldings with an excellent dimensional precision can be obtained. The phenolic resin molding compound comprises: (A) a novolac phenolic resin with an o/p ratio (ortho/para ratio) of 0.7 to 0.9; (B) a novolac phenolic resin with an o/p ratio of 1.1 to 1.3; (C) talc; and (D) a polyethylene or polyethylene/polypropylene copolymer. The amount of (D) the polyethylene or polyethylene/polypropylene copolymer relative to a total weight of the phenolic resin molding compound is 0.5 to 1.5 weight %. It is preferable that the total amount of (A) and (B) is 20 to 40 weight %, and the amount of (C) is 5 to 15 weight %.
