1.aluminium foil roll for heat2.ISO9001:2000; MA; SGS.3.Thickness:0.095-0.220mm4.width:40-1250mmAbout hydrophilic aluminum foil: Hydrophilic aluminum foil occupies 80% volume of the air conditioner aluminum foil, compared with aluminum finstock, the surface of the aluminum foil with corrosion-free and hydrophilic layer, therefore it brings the aluminum foil with function of corrosion-free, anti-mildew agent and no off-flavor; also compared with finstock aluminum foil, its cooling efficient increased 5%, therefore it is more idea air conditioner heat exchange material. It can reduce the noise, guarantee the long & steady hot exchanger results of the air conditioner.
