PROBLEM TO BE SOLVED: To provide a grain composition capable of deformation and molding freely, excellent in shape retention property after molding, extremely low in stickiness to surrounding other members such as hands, clothing and work bench even though having stickiness between grains each other, and being bioinert.SOLUTION: The grain composition contains gains having silicon oxide on a surface and a binder consisting of a mixture of a silicon rubber and a liquid paraffin, where the binder coats the grains and is filled with moderate spaces between grains. The binder adds flowability and stickiness each other. Grains have the percentage content of 93.00 to 97.00 wt.% and compression reversibility of shape retention property-flowability.SELECTED DRAWING: Figure 1 |
