AS-PX50 – A Aramid Polyester tape TSR  is a aramid paper laminated polyester adhesive tape with thermosetting rubber adhesive.
AS-PX50 – N Nomex® Polyester tape TSR  is a Nomex® polyester adhesive tape with thermosetting rubber adhesive.

An enhanced dielectric strength is achieved via laminating the tape with a polyester film. For electrical insulation at high thermal loads and as final insulation.  The result is an F class item (155°C) which joins its excellent electrical and mechanical performances to the Nomex thermal resistance.

• Used in motors as a phase insulator and generally in electrical applications where an elevated thermal resistance is required.
