Polypropylene (PP) is part of the polyolefins family. PP is extremely resistant to chemicals. Furthermore, due to its molecular composition, it does not irritate the skin and is physiologically harmless.
With a density of approximately 0.9 g/cm³, polypropylene is the lightest plastic in the standard range. As a result of these properties and its low water absorption, PP is ideal for lightweight, dimensionally stable food packaging and fittings. |
