What are the properties of polyimide film

Polyimide film is a very practical material, there are many places where it can be used, but for customers and friends who want to buy, we must first figure out what properties the polyimide film has. Here, we Let’s take a look at the introduction below in detail.

ポリイミド薄膜

Polyimide film is widely used in traction motors, submersible motors, nuclear power equipment, high-temperature wires and cables, electromagnetic wires, special electrical appliances, busbar ducts, gas masks, high-temperature flexible printed circuit substrates, flat-panel circuits, and speaker voice coil frames, etc. field. It is the only non-warping polyimide film used for die cutting in China. Thermosetting polyimide has excellent thermal stability, chemical resistance and mechanical properties, and is usually orange. The flexural strength and flexural modulus of graphite or glass fiber reinforced polyimide can reach 345 MPa and 20 MPa, respectively. Thermosetting polyimide has low creep and high tensile strength. The application temperature range of polyimide is very wide, from minus 100 degrees to two or three Baidu. Polyimide is chemically stable.

Polyimide can be flameproof without flame retardant. Common polyimides are resistant to chemical solvents, such as hydrocarbons, esters, ethers, alcohols and chlorofluorocarbons. They are also resistant to weak acids, but they are not recommended for use in strong alkali and inorganic acid environments. Some polyimides, such as CP1 and CORINXLS, are soluble in solvents, which helps to develop their applications in low-temperature spraying and cross-linking.
