WebSep 6, 2024 · The raw material of polypropylene chips used in the melt spinning web is spinning grade polypropylene (PP) chips, and their specific properties are as follows. (1) Melt index (MFI): 25-40 g / 10min for the spunbond method and 400-1500 g / 10min for the melt-blown method. (2) Relative molecular mass distribution width (Mw / Mn): <4 ~ 5. WebThe properties of PP include: Good chemical resistance to acids, alkalis, and most solvents. Resistance to moisture. A high melting point gives it excellent heat resistance. That’s why you’re able to reheat your leftovers in Tupperware without worrying about it melting! It’s lightweight and strong. Plus, it’s a good electrical insulator. tena flex ultima proskin
