ISONOM ® NMN 0881

ISONOM ® NMN 0881

Composition

ISONOM ® NMN 0881  consists of PET-film covered on both sides with calendered Nomex¹ Type 464.

Application

ISONOM ® NMN 0881  is mainly used as a slot liner, slot closure and phase insulation in the production of low voltage motors.
Beside this ISONOM ® NMN 0881 is used as interlayer insulation in transformers and other electrical machines and appliances.

Properties

ISONOM ® NMN 0881 is a combined flexible material of thermal classification 155 °C to 180 °C with excellent mechanical properties like high tensile strength and high edge tear resistance combined with high electrical strength.
ISONOM ® NMN 0881  has a smooth surface which allows trouble free manufacturing of low voltage motors where coil shooting machines are used.
