Product Description

Nomex / Polyester Laminate (NPN212)

1 x Sheet –0.14mm x 900mm x 200mm


Description...  This widely used slot, transformer and coil insulation consists of Nomex Aramid Paper laminated to Polyester film in a three ply configuration, (Nomex/Polyester/Nomex). This produces a material the qualities of which match the needs of many electrical insulation applications.


Applications...  Include and are not limited to - The Insulating Of: Armature Slots, Motor Stator Slots, Inter-phase Barrier Insulating, Transformer Layering, Tesla Coil Forming, and generally most applications that involve or require the insulating of coil windings.

Properties...  The combination of these two materials give excellent mechanical strength with the advantage of high temperature use. Dielectric strength is good and the materials are resistant to most industrial chemicals. This materials can be cut, punched or folded & creased to suit most applications and are also compatible with varnishes and resins.


Classification...  These composite materials are suitable for constant use at 155 degree C and are therefore classified as class F materials.

Application...  Due to their excellent properties these materials are well suited for use as slot linings, coil and phase separation and other similar applications in all types of electrical machinery.

  1. excellent!

    Just wat I needed!
    But why can't I see on the website the bigger sheets 900x400?

  2. Excellent insulating paper

    Posted by Skipmeister on 25th Apr 2020

    This is a really tough insulating paper, ideal for making the slot insulation and slot closers when rewinding motors. This thickness of 0.14mm was ideal for a dual-wound two-speed motor as it enables two separate windings to be insulated from each other in the same slot with good strong insulation. It also takes the insulating varnish well.
