- Polypropylene shows a high mechanical strength and a tensile strength, but a low notched impact strength. 
The mechanical features are better than those of HDPE. It is easy to weld. At minus temperature it can get brittle.
The chemical and electrical properties are very good. 
The continuous operating temperatures ranges between +5℃ and +100℃
