Temperature classification:H(180℃)
1.Specitication
NHN composed of two layers of Du Pont's NOMEX Brand Paper and one
inner layer of polyimide film to provide superior electrical mechanical,thermal
properties and high mechanical strength.
It is suitable for insulation of slot ,phase,turn-to turn and liner
of Hclass motors and generators.

3.Dimension
NHN combined flexible material can be supplied in roll form ,reel
form or sheet form.The weight of each reel is about 30-60kg depended
on length required by customer .Width of each reel is about 500mm.
4.Storage
NHN should be stored under 40 in clean and dry warehouse,stay
away from fire,heat and avoid direct sunshine.The storage life
is 12 months from the date of dispatch.If the storage time is
over 12 months ,the product should be tested and pass all the
specification before use.
