Polyester film/polyester fiber non-woven fabric flexible composite material
(F-DMD) is made from high melting point polyester film and hot-rolling
polyester fiber non-woven fabric. The polyester film and polyester non-woven
fabric are bonded by F-class adhesive. Characters It
is Class F insulating material. This
product has high mechanical strength, excellent electrical property, and
immerse the function. ApplicationIt
is suitable for slot insulation, interphase insulation and liner insulation in
Y2 and other F-class electrical motor and electric apparatus. Properties | Units | Values | Nominal
