- -6641 CLASS F DMD GREEN INSULATION PAPER fabric flexible Laminate is a three -layer flexible composite material.
--The thicker Polyester film you choose, the higher electrical strength is.
2.Features:
--Insulation class: F class (155 °C)
--Polyester film/Polyester fiber non-woven fabric flexible Laminate has high dielectric properties, tear strength and tensile strength, good impregnation performance
--As slot, interturn and liner insulation for E-grade motors, generators and electric appliances. The polyester film for electrical industry has high dielectric properties, tear strength and tensile strength, good impregnation performance
--6641 / F grade DMD polyester film polyester fiber composite foil for motor, electrical stator winding in the slot insulation, liner insulation and turn to turn insulation.
--F-class DMD insulation paper is also used in dry-type transformer coil insulation layer, the end of insulation, liner insulation.
3.Availability:
--Form: roll, sheet, strip
--Colur: Blue, green, white and pink. Special colours can be provided on request. --Four layers can be produced on request.
