Polypropylene is a semi-crystalline engineering plastic widely used in practically all industrial sectors, especially in the automotive, chemical, food and textile industries.
It is one of the plastics with the highest production worldwide due to its versatility and good recyclability.
It stands out mainly for being the plastic in common use with the lowest density, approximately 0.9 g/cm3, as well as for its excellent mechanical properties and high chemical resistance.
Sinterit’s polypropylene powder is the first SLS printing polypropylene compatible with compact SLS 3D printers. It is a multi-purpose material that complements those already available within the Sinterit range.
