Product Details

Flexible composite insulation material NMN

Flexible composite insulation material NMN is made of two layers of Nomex paper and one layer of PET film, coated with grade H thermal upgraded adhesive. It has high mechanical properties, dielectric and thermal upgrade properties, and low dissipation factor. It can be used as turn and backing insulating material in grade F and grade H transformers, motors and other electrical appliances. The NMN can work for a long time in a 180℃ environment。

Recommended width: 910mm and narrower. Tailor-made width is available.

Storage

The flexible composite insulation material NMN should be stored in dry, clean and well-ventilated warehouse under 30℃. The fire, heat sources and direct sunshine should be avoided.
