Product Introduction:

Advanced Institute Technology produces PET and PI low-temperature electric heating films, polyimide high-temperature electric heating films, and infrared PI films; Suitable for daily life insulation and heating, it can also be used in conjunction with various precision electronic instruments for heating solutions.

Infrared PI film has excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and dielectric resistance. It can be used for a long time in the temperature range of -269 ℃~280 ℃, and can reach a high temperature of 400 ℃ in a short time, making it easy to process and shape;

Product Structure/Material:

poly

Product nature/features:

01 Excellent heat resistance

The decomposition temperature of polyimide generally exceeds 500 ℃, sometimes even higher, making it one of the most thermally stable organic polymers currently known;

02 Excellent mechanical performance

The tensile strength of unreinforced matrix materials is above 100MPa, while the tensile strength of infrared PI films prepared with maleic anhydride is 170MPa, and that of biphenyl polyimide can reach 400MPa;

03 Good chemical stability

Polyimide materials are generally insoluble in organic solvents, corrosion-resistant, and resistant to hydrolysis. By changing the molecular design, different structural varieties can be obtained;

04 Good radiation resistance performance

After being irradiated with a dose of 5 * 109rad, the strength of polyimide film remained at 86%;

05 Good dielectric properties

The dielectric constant is less than 3.5. If fluorine atoms are introduced into the molecular chain, the dielectric constant can be reduced to around 2.5, the dielectric loss is 10, the dielectric strength is 100-300kv/mm, and the volume resistance is 1015-17 Ω· cm;

Product application areas:

Used in the fields of drying equipment, vacuum heating, drying of Chinese herbal medicine, agricultural and seafood products, new energy heating plates, military equipment heating, medical equipment heating, agricultural greenhouses, saunas, bathroom heating and other product areas;
