Why does my parts made of Polypropylen break?
(OP)
Hi all,
I have parts made of polypropylen 7728 and they break easily. I'm wondering if improper storage can be the cause of the breakage. We are situated in Quebec, so the temperature can go below 0°C.
If you have any ideas, please let me know,
Thank you,
Iboivin

I am not familiar with current grade numbers, so I don't know your specific grade.

I'm not familiar with your grade of PP. If it an easy flow grade (MFI > 15), then its tensile strength an impact resistance might not be sufficient for your application. Try a PP grade with a lower MFI.
