Nomex® Laminates – AVAILABLE WITH US
Nomex® Polyimide Nomex®
Nomex® Polyimide Nomex® is a triple layered laminate with polyimide film sandwiched in between two layers of DuPont™ Nomex® aramid paper bonded with a high temperature adhesive system. The product is designed not to delaminate or blister at elevated temperatures.
This semi rigid laminate exhibits a high dielectric strength, as well as good initial tear and tensile strengths. The high abrasion properties allow the product to be inserted easily in the slot portions of a stator without damaging the insulation properties.
Application
These laminates find a popular use in the manufacture and repair of motors and generators of various ratings and temperature class. Popularly used as slot liners in stators, as wedges and phase insulation in motors and generators, as well as special H class motors.
NKN Laminates Available With Hatim Dielectrics
These laminates are available in standard widths of 900mm in continuous rolls in various thickness and constructions. Slitted Tapes to specific sizes are also available upon request to facilitate auto slot insertion process in small stators.
Shelf Life
Nomex® Polyester Nomex® exhibits a shelf life of 12 months from date of manufacture when stored at 25°C temperature and 50% relative humidity.
