Neat and reinforced polyamides 46 examples of properties

5 Semi-aromatic polyamides, polyphthalamide (PPA), polyarylamide (PAA), transparent amorphous polyamide (PA-T) 

The following properties often concern engineering PAs. Transparent grades often have lower characteristics but are among the performance thermoplastics. 

Applications are always technical, based on mechanical and thermal performances or on transparency and mechanical behaviour, for example  

There are only a few producers and the number of grades is limited  

The costs are higher than those of PA 6 and 66 and, as for all plastics, fluctuate greatly with the crude oil price.
