NKN – Laminat aus Nomex-Polyimidfolie-Nomex
NKN is a three-layer insulation made of polyimide film with Nomex® 410 on both sides, for the highest thermal demands.
Since both components, polyimide film and Nomex®, meet the highest temperature requirements, two-layer combinations are also possible as special types.
Since polyimide film has a higher price than Nomex, the Nomex cover is adapted to achieve different thicknesses and the film thickness is retained.
Applications of NKN
NKN is used in high-efficiency electric motors as Nutisolation, Phase isolation as well as Cover slideused. Furthermore, NKN can be used in transformers and chokes as core, layer and cover insulation if very high temperature resistance is required with simultaneous mechanical stress.
NKN can also be feathered when it is called feathered band should be used.
Stamped parts from NKN
The Dr. Dietrich Müller GmbH produces stamped parts in various designs from NKN.
Datasheets for NKN
The basis weights for the material NKN and other technical data can be found in the data sheets for NKN.
The flexible GKG laminate consists of a polyimide film coated on both sides with glass fabric.
The polyimide film offers excellent electrical insulation at high temperatures, while the glass fabric offers excellent mechanical strength, resin absorption and thermal shock resistance.
Its properties include its high heat resistance above 200 ° C and its electrical and mechanical properties, the latter being particularly easy to tear thanks to the mechanical reinforcement of the glass fabric.
The adhesive used has high heat resistance (class 200) and, being fully polymerized, is compatible with all types of resins and paints.
Optionally, this laminate can be provided with other combinations of components: polyimide film of 0025, 0050, 0075 and 0125 mm and thicknesses of other glass fabrics.
Stamped parts from GKG
The Dr. Dietrich Müller can process the GKG laminate into punched parts and strips.
