Abstract
PURPOSE: The titled material capable of forming a molded article with high specific gravity without lowering moldability, obtained by blending a novolak type phenolic resin with Portland cement, followed by powdering.
CONSTITUTION: A precondensate of novolak type phenolic resin is blended with 40W80wt% of Portland cement as a filler and granulated. A composition with a high specific gravity of not less than 2.0g/cc can be obtained.
USE: A turn table of speaker.
