<p>PURPOSE: Polyolefin-group resin laminated foam is provided to obtain excellent washing performance in washing contaminant on surface of minute electronic instrument even when contaminant is transferred in the minute electronic instrument. CONSTITUTION: Polyolefin-group resin laminated foam comprises polyolefins resin layers laminated in one side of the polyolefin-group foamed resin article layer. A hydrophilic compound more than 1 which is selected in a surfactant in which the polyalkylene oxides and hydrophile-lipophile balance(HLB value) are 8 or greater is added to the polyolefin-group resin layer. The ratio of the hydrophilic compound is 0;5 ~ 20 parts by weight to 100 parts by weight of the polyolefin resin.</p> |
