Nokamex laminates are high-performance insulating materials. Nokamex Triplex (NKN laminated film) multi-layer laminated technical grade film consists of a polyimide film and two Nomex aramid papers calendered on both faces.

The excellent dielectric and thermal properties of the polyimide film and the impressive thermal and mechanical properties of the Nomex layers combine to produce a very high-quality insulating material. The outside layers of aramid paper protect the polyimide film from the effects of hydrolysis and mechanical loading. The high volume resistivity and dielectric strength of the laminate are not affected at temperatures up to 200°C. The polyimide film in these 2- and 3-layer laminates gives the product high tensile strength and good tear resistance. The Nomex laminated paper provides durable thermal stability and improves the tear resistance.

Nokamex is widely used in the manufacture and repair of motors and generators of various sizes and temperature classes. Since generators demand higher levels of performance than H-class applications (180°C), they account for one of the most important applications of this laminate, along with locomotives.

We are commited to deliver converted or cut materials in their most finished possible form

The purpose of laminating is to combine materials to enhance the properties of a single film.

Lamination is a process whereby an adhesive layer is applied to a material.

ADDEV Materials uses various processes to cut all soft, flexible products into specified formats such as A4, A3 or any other dimensions.

ADDEV Materials examines customers’ requirements to provide fully adapted custom design to implementation solutions for parts cut to the required shape.
