Example of polyamide-imide formula

Polyamide-imides are handicapped by the cost (justified by the performances), a high density, the small numbers of grades and sources. PAI can slowly absorb some water in a wet environment, which has a plasticizing effect and can lead to a significant linear expansion. 

They can be classified according to the type of processing, specific properties, or targeted applications  

As for all plastics, the costs fluctuate greatly with the crude oil price, and are only given to provide an idea. They are generally of the order of several tens of Euros to a hundred Euros per kilogram. 

All the molten state methods are usable but the main ones are extrusion, injection, compression, machining. 

The consumption of polyamide-imide varies according to the country and the source, but is too low to be listed in statistics. It can be approximately divided into four main sectors
