Polyethylene Separator with Laminated Glass Mat for Heavy Duty and Start-Stop Applications ENTEK PE Glassmat separator consists of a 100% glass fiber retainer mat laminated to the polyethylene separator. This is achieved by using a purpose-built laminaƟng machine to apply a special adhesive to the ribs of the separator, and laminaƟng the glass mat to the separator ribs. The resultant laminated separator material is supplied to the customer in roll form. It can therefore be used on enveloping machines in the same way as the standard polyethylene separator material. ENTEK PE Glassmat should be specified in baƩery applicaƟons where an excepƟonally heavy duty cycle is anƟcipated e.g. regular deep discharges. Examples include buses, taxis, commercial vehicles etc. The glass retainer mat in contact with the posiƟve plate helps to protect the acƟve material against shedding in deep discharge and high vibraƟon condiƟons. ENTEK PE Glassmat helps to extend baƩery life under arduous operaƟng condiƟons, e.g. high ambient temperatures and severe vibraƟon.
