Nomex laminates have excellent electrical and mechanical strength. The most common types of laminate insulation based on Nomex® paper are NMN and NKN Custom laminate solutions can be designed to meet performance requirements of specific applications.
Nomex laminate type NMN
Type NMN is a laminate with polyester film and Nomex® paper. Type NMN laminates made with Nomex® papers are used in UL systems typically up to 180°C. These laminates are broadly used in the production and repair of motors, generators of many sizes and temperature classes. The most important applications for these laminates are slot liners, wedges and phase insulation in Class H motors and generators, as well as in large and specialty Class F motors.
Nomex laminate type NKN
Type NKN is made by laminating polyimide film with Nomex® paper. These laminates are typically used in motors and generators that operate in excess of Class H temperature requirements. There are a number of insulation systems recognized by UL that include these laminates for temperature classes up to and including 220°C.
