Flexible Laminates NMN NPN

Flexible Laminates NMN-NPN

Flexible Laminates NMN-NPN

The flexible laminates are provided by Ganapathy Industries in NMN/NPN types. These top grade products have par-excellent heat resistance and are provided in the forms of roll, sheet, and strips. The Nomex Paper / Polyester Films / Nomex Paper Flexible composite material is manufactured in two layers of Du Pont Nomex paper alongside the one layer of polyester film. Thermal stability and improved propagation tear strength is achieved by using the Nomex paper. The Nomex flexible laminates are suitable for use in electrical appliances with working temperatures of up to 155°C class F. Some features of flexible laminates are given below:

  • Outstanding heat resistance
  • First-rate mechanical strength and dielectric property
  • High stiffness
  • Good resistance to overload and cutting
  • Highly compatible with insulation varnish

Flexible Laminates Application:

It is used as interturn, slot and liner insulation for F-grade electrical motors and other electric appliances. We offer it in the forms of roll, sheet, and strips.
