PROBLEM TO BE SOLVED: To eliminate static electricity by extrusion molding composition containing thermoplastic elastomer, soft vinyl chloride resin composition and nonionic water absorptive resin. SOLUTION: The glass packing material 1 comprises composition containing 100 pts.wt. of thermoplastic elastomer and (or) soft vinyl chloride resin composition and 7 to 25 pts.wt. of nonionic water absorptive resin. The nonionic resin is a component for imparting water absorption properties to the material 1 and antistatic properties. When the using amount of the nonionic resin becomes less than 7 pts.wt., the water absorption properties of the material 1 become low, and hence the antistatic properties also becomes low. On the other hand, when it exceeds 25 pts.wt., the water absorption rate becomes excessively high, and when it absorbs the water of large quantity, the surface becomes sticky or is deformed. |
