B, F, H grade flexible composite panels have sound dielectric performance, high heat resistance and mechanical strength. They are mainly used in various thermal ratings of low voltage motors, electric appliance slots and convolution liner insulation. They can also be used for layer insulation in the middle of the transformers. Model numbers include JF-6520-50, JF-6630, JF-6630A, JF-6632, JF-6633, JF-6640, JF-6641, JF-6642, JF-6650, and JF-6652. they are available in thickness of 0.15mm, 0.18mm, 0.20mm, 0.23mm, 0.25mm, 0.30mm and 0.35mm.
