An elastomer composition containing a matrix of a biomass plastic and crosslinked natural rubber particles dispersed like islands in the matrix.
A method for producing an elastomer composition comprising the steps of;
- kneading a biomass plastic, natural rubber, and a rubber crosslinking agent at a temperature not lower than the melting temperature of the biomass plastic and not lower than the crosslinking temperature of the rubber crosslinking agent, and
- dispersing crosslinked natural rubber particles like islands in the matrix of the biomass plastic.
An eraser made of an elastomer composition containing a matrix of a biomass plastic and crosslinked natural rubber particles dispersed like islands in the matrix of the biomass plastic.
An eraser comprising an elastomer containing a matrix of a biomass plastic and crosslinked natural rubber particles dispersed like islands in the matrix and a vinyl chloride resin.
A method for producing an eraser comprising the steps of;
- melting and kneading an eraser of an elastomer eraser composition and an eraser of a vinyl chloride resin eraser composition, and
- molding the kneaded mixture.
