HDPE Extrusion what MFI value for best production efficiency

[Franck YOUDJEU]

I have a small scale corrugated pipe manufacture, so we extrude HDPE pellet recycled material to make corrugated pipe. I'm wondering about the effect of MFI value(g/10min) on production efficiency.
I have a choice from supplier between MFI of 0,25 or MFI of 1,6. Which one shall I choose for my production.
I need your help please

Hi, MFI 1.6 will be more suitable for you. MFI 0.25 is more for thin films. But all production lines have their own optimal requirements for raw materials to make the production process the most efficient. So it is a good idea to read the production line's documentation or to contact the manufacturer.

Thank you very much, I'm actually getting them tested each in order to have more fine feedback.
