Chart showing new PP grade properties

The new PP grade is a fully recyclable mono-material, which represents an alternative to a conventional PP core/polyethylene (PE) sheath bicomponent solution. Polypropylene (PP) is widely used in textile applications such as carpets and diapers. The end-uses and production processes require polymers with the highest purity. PP is produced using a Ziegler–Natta catalyst (also called …
