Flexible Laminates

ISONOM ® NKN 8 0886


ISONOM® NKN 8 0886 consists of Polyimide film (e.ge. Kapton'), covered on both sides with calendered Nomex² type 416.


ISONOM® NKN 8 0886 is mainly used as a slot liner, slot closure and phase insulation in thermal high stresses electrical motors.
ISONOM® NKN 8 0886 is also used as interlayer insulation in transformers and other electrical machines and appliances.


ISONOM® NKN 8 0886 is combined flexible material of thermal rating class 180 – 200°C with good mechanical properties like high tensile strength and high tear resistance combined with high electrical strength.

ISONOM® NKN 8 0886 has smooth surface which allows a trouble free manufacturing of low voltage motors where coil inserting machines are used.
