Examples of part tolerances for normal and precision classes

The following graphs and tables make it possible to quickly visualize some significant characteristics and to roughly position certain thermoplastics and their composites with respect to each other. The goal is only to make a first, very approximate, pre-rating. The reader must then consult the detailed monographs  

Remember that the goal of the following figures is only to make a first, very approximate, pre-rating. 

Each raw polymer has its set of interesting properties that can be modified in order to adapt to the requirements of each customer and application. Several routes are suitable  

For some specific thermoplastics, crosslinking is used to improve some properties induced by the formation of the 3D network. 

Thermoplastic families are diverse but their number is limited and often there are wide gaps between the properties of two basic polymer types. To bridge the gap, two polymer families can be mixed if they are compatible or if it is possible to compatibilize them with a third material.
