ELIFLEX 21 TU 3491-003-00214639-01 consists of one layer of heat-resistant polyimide film and one
a layer of polyethylene terephthalate film.
Not only has excellent dielectric characteristics, but also excellent flexibility, excellent durability
tensile loads.
ELIFLEX is used in the manufacture and repair of electrical machines of class F heat resistance and has a high resistance to aging and a long service life.
Resistant to aggressive substances.
ELIFLEX is used as groove insulation for compressors of refrigeration units with an operating temperature of up to+120°C in an environment of R 12 freon and HF 12-16 oil and for mechanized insulation of stators.
Properties:
good flexibility and strength
excellent electrical insulating properties
great resource of work
high reliability
Size: 300 x 200mm, thickness 0.25mm
Electrical insulating film-containing material ELIFLEX 21X, 212X
Eliflex 21Xis a two-layer composition consisting of a polyester film, glued on one side with a polyimide film. Eliflex is used for groove insulation, wedge cover of low-voltage electrical machines in an insulation system of heat resistance class F (155°C), for groove insulation of electric motors of compressors of household refrigerators with an operating temperature of 130°C. Suitable for mechanized insulation of stators. Freon oil resistant insulation. Service life 30,000 hours.
Eliflex 212Xis a three-layer composition consisting of a polyester film, pasted over on both sides with a polyimide film. Eliflex is used for groove insulation, wedge cover of low-voltage electrical machines in an insulation system of heat resistance class F (155°C), for groove insulation of electric motors of compressors of household refrigerators with an operating temperature of 130°C. Suitable for mechanized insulation of stators. Freon oil resistant insulation. Service life 45,000 hours.
