MPI adhesive free polyimide is a type of adhesive free polymer material obtained by modifying traditional polyimide. It retains the excellent properties of polyimide, such as high thermal stability, excellent electrical insulation performance, and good mechanical strength, while removing the adhesive layer, resulting in purer performance.

High thermal stability: MPI adhesive free polyimide can withstand stress in high-temperature environments, with a thermal decomposition temperature typically above 500 ℃, making it suitable for high-temperature working environments.
Excellent electrical performance: With extremely low dielectric constant and dielectric loss, as well as high dielectric strength, it is an ideal choice for electrical insulation materials.
Good mechanical performance: It has high tensile strength and toughness, can resist external impact and tearing, and maintain structural integrity.
Chemical stability: It has good stability against various organic solvents and chemical reagents, and is not easily corroded or dissolved.
Low water absorption rate: helps maintain the electrical and mechanical stability of materials in humid environments.

MPI adhesive free polyimide is widely used in multiple fields due to its unique performance characteristics:
Aerospace: Used for manufacturing electrical components and structural materials in high-temperature working environments, meeting the demand for high-performance materials in the aerospace industry.
Microelectronics: As a high-performance insulation layer and protective layer, it is widely used in integrated circuits, chip packaging, and other fields to improve the reliability and stability of microelectronic devices.
Flexible display: Utilizing its excellent flexibility and transparency, it is used to manufacture flexible display screens and substrates for wearable electronic devices, promoting the development of flexible display technology.
In other high-tech fields such as new energy, medical devices, environmental protection, etc., MPI non adhesive polyimide also shows a wide range of application prospects.
