Question about Purefil Filament

TPU: The so-called thermoplastic polyurethane (TPU) is an elastomer (synthetic plastic) that is characterised by its high flexibility and resistance during further processing and combines the properties of thermoplastics and elastomers.

TPC: Thermoplastic elastomers (abbreviation TPE or TPR from Thermoplastic Rubber, occasionally also called elastoplastics) are plastics that behave similarly to classic elastomers at room temperature, but can be plastically deformed when heat is applied and thus exhibit thermoplastic behaviour.
