My bad. Should have typed tecnopolymer. Tired!
A quick hit from Google:
Technopolymer
With increasing temperature and once the softening point is exceeded, this group of technopolymer melts, can be heat distorted and solidifies again after cooling. This process can be repeated any number of times. Unlike Duroplast, there is no chemical reaction during processing.
Technopolymer materials can be subdivided into amorphous and partially crystalline plastics. The disordered structure of amorphous materials allows the production of transparent components by injection molding right through to crystal-clear parts. Partially crystalline thermoplastics have a structure resulting in enhanced mechanical properties and temperatures of use.
The wide variety of different technopolymers and the options of modifications allow the production of “tailor-made” construction tools with respect to mechanical properties, chemical resistance, temperature resistance and different colors.
