Polyethylene Separator with Laminated Glass Mat for Heavy

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.
