Modified Polyimide (PI) Materials: Customized Solutions for Specific Working Conditions

Modified Polyimide (MPI) is a material whose chemical structure has been adjusted through various methods to enhance its mechanical properties, high temperature resistance, electrical insulation properties, chemical corrosion resistance, and low friction performance.`

Allstar Material Modified Polyimide PI Performance Advantages

When pure PI performance cannot meet practical application requirements, PI modification is performed to achieve conductivity or anti-static properties, friction coefficient reduction, elasticity, and processing performance simultaneously.

High Temperature Resistance

In high or extremely low temperature environments, the traditional temperature range of pure PI is too narrow, and higher requirements are needed for applications such as conductivity. To improve this limitation, various properties can be enhanced through Allstar Material’s modified PI materials, which accurately meet temperature requirements through additives, providing wide temperature ranges.

High Electrical Insulation

Among insulation materials, PI application is in the field with the highest insulation requirements. To meet actual user needs, PI must have electrical properties, strength, and extremely high performance that exceed standards. Allstar Material’s modified PI features customizable high voltage resistance and other properties to ensure production safety and product quality with outstanding insulation capability.

Low Friction Coefficient and Self-Lubricating Properties

For various equipment requiring high lubrication and reduced wear component friction coefficients, component overheating, component failure, and overall performance improvement, Allstar Material has developed modified PI through independent research, which is oil-free and self-lubricating, suitable for a wide range of applications, providing excellent hardness and low temperature performance.

Mechanical Strength and Dimensional Stability

For example, in applications for aerospace components, if pure PI’s rigidity and strength are insufficient in the project’s working conditions, it may cause various problems. Proprietary additives can be used to fully meet or exceed target usage conditions and improve dimensional stability. Allstar Material’s modified PI can undergo no deformation, no swelling, or no contraction after long-term use under high-precision mechanical cutting conditions.
