electrical polyster nonwoven

Introduction Of Product

Electric polyester fiber non-woven fabric (7031) has high heat resistance, excellent impregnation and dielectric properties, cloth smooth, small thickness deviation, high tensile strength and neat in appearance.
Widely used in composite material (DMD, DM, dMDM), mica tape reinforcing material, electrical laminated products, insulation varnished cloth, electrical appliances, transformer, motor coil end bandaged.
Also for small, soft cable, civilian electrical cable, communication cable and instead of various types of paper insulation material to be used.
