GRID PASTING PAPER FOR BATTERY INDUSTRY The BAT grades are composed of the substances between 13 and 15gsm. They are produced as a whole with a selected wood cellulose bleached fibres that are suitable for the use of the final product. Battery paper tissue (BAT) has been designed to be used on automatic pasting lines for Metal Expanded an Continuous Casting lines. Water absorption of BAT paper grades has been tested to assure a good stickiness of the paper on paste during pasting and curing process. Mechanical characteristics (Dry and wet tensile strength) assure good runnability on pasting process lines. Low content of metal compound and chlorine allow the best results on Battery Electrical performance. These BAT grades must be porous in order to adhere the paper correctly to the plate/sheet, both in damp and wet conditions.
