How does polypropylene PP differ from polyamide HP PA 12?
Polyamide and polypropylene have many common physical properties, but there are also some differences, as provided below.
- The melting point of PA 12 powder is 187°C, and that of PP is 138°C.
- The bulk density of PA 12 powder is 1.01 g/cm³, and that of PP is 0.34 g/cm³ (polypropylene products are lighter than polyamide ones).
- The hardness (Shore D) of polyamide is 80, and that of polypropylene is 68 (products made of polyamide are stronger).
