Details:

 

Nomex Kapton NK and NKN are duplex and triplex insulation laminate materials made of calendered DuPont™ Nomex bonded to polyimide film with a proprietary high temperature adhesive. The materials are designed not to delaminate or blister at high temperatures. The polyimide film in these 2 and 3-ply laminates contributes high dielectric strength, as well as good initial tear strength and tensile properties. The Nomex paper provides long term thermal stability, as well as improved propagation tear strengths. Excellent Class H insulation.

CGS can also slit,sheet and die cut material to your specification, saving your time and materials.

Colors

Nomex usually whitish, kapton polyimide usually brownish

Nomex Kapton Applications

 

Nomex Kapton are highly performing solutions for the insulation of electric motors and more generally rotating machines with working tem­peratures up to 200°C. Such as slot liners, wedges and phase insulation in motors and generators which have thermal requirements above Class H applications.
