insulating materials transformer nkn nhn


NK and NKN laminates are duplex and triplex laminates constructed of calendered NOMEX® paper bonded to polyimide film with a proprietary high temperature adhesive system. These laminates will not 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 calendered NOMEX paper provides long term thermal stability, as well as improved propagation tear strengths.

Broadly used in the manufacture and repair of motors and generators of many sizes and temperature classes. The most important applications are for slot liners, wedges and phase insulation in motors and generators which have thermal requirements above Class H applications.

Hechin can custom slit-to-width rolls, die cut and punch press custom parts, and sheet NK and NKN laminates to your specification, along with other customized solutions. Request your quote for custom parts today!
