Abstract
Tablets of thermoplastic resin and filler, in which the compositional ratio of the two is so controlled that the thermoplastic resin accounts for from 1 to 40% by volume and the filler for from 60 to 99% by volume based on the sum of the two, 100% by volume, are obtained by compression-molding thermoplastic resin powder and filler into the tablets, or melt-kneading thermoplastic resin and filler followed by compression-molding the powder of the resulting composition into the tablets. The filler content thereof is high, heretofore unknown in the art, and the tablets efficiently exhibit the properties of the filler therein.
