<p>[Problem] To provide a plastic eraser which has a superior erasing property, and has an extremely low environmental load. Further, to provide a plastic eraser composite body and a production method therefor, wherein such a plastic eraser is filled into a porous structural body made of an organic polymer. [Solution] A plastic eraser comprises a vinyl chloride based resin as a base resin, and a combination of 4,5-epoxy-1,2-cyclohexanedicarboxylic acid bis (2-ethylhexyl) and diethylene glycol dibenzoate as a plasticizer, wherein 25 to 60 % by weight of the base resin, and 30 to 60% by weight of the plasticizer combination are contained, the ratio of the diethylene glycol dibenzoate in the plasticizer combination is in the range of 5 to 60% by weight, and the eraser has a hardness in the range of 55 to 75 and a gel hardness in the range of 3.0 to 6.0 kgf.</p> |
