Thanks to all of you!
We will try to use the petroleum-based products. We will do some tests. We want to be able to use the test on site where technicians will need to change the part.

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.

Thank you,
