<p>PURPOSE:To obtain the formed desiccant having high moisture absorptivity and water retentivity and excellent in forming adaptability by kneading a specified desiccant with a thermoplastic resin. CONSTITUTION:5 to 400 pts.wt. of at least one kind among magnesium sulfate shown by MgSO4.nH2O where 0<=n<=3), aluminum oxide, barium oxide, calcium oxide and silicon oxide is added to 100 pts.wt. of a thermoplastic resin to obtain a formed desiccant. A foaming agent can be added to the formed product, and at least one kind of laminating material can be laminated. The desiccant can be formed into the film, sheet, bag and pellet. The formed desiccant has high moisture absorptivity and water retentivity, and easily formed into an optional shape in accordance with its usage.</p> |
