TPI (Thermoplastic Polyimide)

 

TPI polymer is an amorphous when it is made by injection molding. Amorphous polymer shows better dimensional stability than crystalline or semi-crystalline polymer.

On the other hand, special treatment for amorphous TPI makes the crystallinity increasing. When the crystallinity of TPI increases, the thermal property is largely improved: the heat deflection temperature of natural TPI shows 315°C.

It is possible for PBI Advanced Materials to make an amorphous TPI by injection molding and a highly crystallized TPI by compression molding.
