The decomposition temperature of polyimide resin is generally around 450°. It is one of the polymers with good high-temperature resistance. It can withstand extremely low temperatures. For example, it will not brittle in low-temperature liquid nitrogen of -269°. Mechanical properties: elastic modulus 3-4GP, fiber up to 200GP. It is a self-extinguishing polymer with a low smoke rate. The grade can reach UL94V-0/5V and can withstand ordinary organic solvents. The cured product is stable to acids and alkalis. The insulation grade can reach C level. It still maintains good performance after a large dose of radiation. Excellent electrical and mechanical properties, the friction coefficient can be lower than 0.02. Dimensionally stable at high temperatures, it can be used to make tableware and medical utensils that can withstand thousands of reuses;

Polyimide resin, this advanced composite matrix, has many unique properties, making it occupy an irreplaceable position in applications in the aerospace and electronic and electrical fields. Polyimide resin has excellent high temperature resistance and can maintain stable performance at extremely high temperatures, which is crucial for the aerospace industry. In high-speed moving objects such as airplanes and rockets, materials need to withstand extremely high temperatures and pressures, and polyimide resin can meet this demand.

Polyimide resin also has excellent electrical insulation properties. In the electronic and electrical field, the insulation properties of materials are crucial. It can ensure that electronic equipment can operate normally in high-voltage and high-current environments without dangerous situations such as short circuits or electric shocks. Polyimide resin is widely used in the manufacture of electronic components, wires and cables, and integrated circuits.

Polyimide resin also has good mechanical properties and chemical stability. It is not easy to deform or age, and can maintain its performance and shape for a long time. Polyimide resin can still show stable performance in harsh environments, such as high temperature, low temperature, strong radiation, etc., which makes it more widely used in aerospace and electronic and electrical fields.
