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

Modified Polyimide (PI) is an optimization of standard PI materials. When the performance of pure PI cannot meet the requirements of specific working conditions, modified PI—achieved through the addition of fillers (such as graphite, glass fiber, PTFE) or special manufacture processes—significantly improves PI's wear resistance, conductivity, self-lubrication, strength, or processability.

Advantages

Performance Advantages of Allstar Material Modified Polyimide (PI)

When pure PI performance fails to meet actual application demands, modified PI holds significant advantages regarding wear resistance, conductive or antistatic properties, friction coefficient, mechanical strength, and processing performance.

Wear Resistance

High Wear Resistance

In high-friction, high-speed, or abrasive environments, pure PI components may wear too quickly, leading to frequent replacements, more downtime, and higher operating costs. Allstar Material’s modified polyimide, available wholesale from China, improves lifespan and stability, reducing costs and enhancing efficiency.

Conductive or Antistatic Properties

Conductive or Antistatic Properties

In electronics, semiconductor manufacturing, and hazardous environments, static buildup on pure PI can cause damage, dust attraction, or safety risks. Allstar Material’s modified PI offers controlled conductivity and antistatic performance, ensuring safety and quality for specialized insulation needs.

Low Friction & Self-Lubrication

Low Friction & Self-Lubrication

In sliding or rotating parts, pure PI’s high friction causes energy loss, heat, and wear. Allstar Material’s modified PI with PTFE or graphite ensures low-friction performance, even with minimal lubrication, improving efficiency and lowering maintenance.

Strength & Stability

Strength & Stability

In high-stress or wide-temperature applications, pure PI may lack sufficient strength or stability, leading to deformation or fracture. Allstar Material enhances PI with glass or carbon fiber to improve mechanical performance and maintain dimensional stability under stress.
