Kapton Heater Description:
Kapton insulated heaters are available in a variety of shapes, sizes, and wattages. Polyimide Film offers a high degree of resistance to chemicals, and has excellent outgasing properties in high vacuum environments.
Polyimide is an organic polymer with very high dielectric capability and thin profile, while providing superior resistance to most solvents, oils, and radiation. In connection with these features, kapton heater is very ideal for applications with space and weight limitation, or where the heater will be exposed to chemical or oil.
Kapton heater also allows easy visual inspection on the internal structures. Pressure-sensitive adhesive (PSA) backing surface is standard, but special adhesives or mounting holes can be customized as customer requirement.
PI electric heating film of polyimide film is made of polyimide film as outer insulator and Ni Cr alloy etched heating plate as inner conductive heating body by high temperature and high pressure heat bonding. Polyimide electric heating film has excellent insulation strength, excellent electrical strength, excellent heat transfer efficiency and excellent resistance stability, so it is widely used in the field of electric heating.
Product features:
Good flexibility, flexibility, fast preheating speed and long service life.
Ultra thin: only 0.2mm in thickness, surface shape. The bending radius is about 0.08mm.
Variety: it can make all kinds of resistive circuit components with small area.
Uniform heating: the resistive circuit is evenly arranged, the thermal inertia is small, and it is in close contact with the heating body, and the heating speed is fast. It has very low saturated vapor pressure and low outgassing property with insulating materials.
Easy installation: with double-sided adhesive tape, it can be directly pasted on the surface of the heating body.
Long safety life: graphic design, low power load and long service life compared with other heating wires. Good insulation.
High temperature and high pressure test: it can be used for a long time at 200 ℃. It has passed 2500V high voltage test.
