5. Developments
Research and development efforts in the polyimide sector are many and varied. Here are just a few examples of developments, taken from recent scientific literature. The list is by no means exhaustive.
5.1 Use of polyimides as additives in fluoropolymers
The incorporation of 5-30% polyimide in powder form into fluoropolymers (PTFE) increases abrasion resistance. This additive is effective at high Pv coefficients in many fields of application, with or without lubrication

Developments
Economic data
Because of their high price (around thirty times that of polyamides), the market for condensation polyimides is still limited to high-performance applications, and tonnages consumed remain low, even though this market is growing steadily.
The largest market for polyimides is in the United States, with the fastest-growing sectors being film and fibers.
In Europe, the key sectors...
