All Products
Polyimide film PI electrothermal film is made of polyimide film as the outer insulator and Ni-Cr alloy etched heating film as the inner conductive heating element. It is heat bonded at high temperature and pressure. Polyimide electrothermal film has excellent insulation strength, excellent electrical strength, excellent heat conduction efficiency, excellent resistance stability, so it is widely used in the field of electric heating.
Product features:
◆ Good softness, flexible, fast preheating speed and long service life.
◆ Thin: the thickness is only 0.2mm, planar. The space is small, and the bending radius is about 0.08mm.
◆ Varieties: can make all kinds of small area of the resistance circuit components.
◆ Uniform heating: uniform distribution of resistive circuit, small thermal inertia, close contact with the heated body, fast heating speed. It has very low saturated vapor pressure with insulating material and low air release.
Easy installation: with double-sided adhesive tape, can be directly glued on the surface of the heated body.
◆ Long safety life: Graphic design, low power load and long service life compared with other heating wire heating plates. Good insulation.
◆ High temperature resistance, high pressure test: can be used at 200℃ for a long time. And pass 2500V high voltage test.
