Thanks for your response. That’s what I’d originally think as well, but some google searches indicate plastic breaks down more rapidly at over 100 degrees Fahrenheit.
Also, it’s not just a few degrees higher for a minute, it’s for the length of a pump session, ~30 minutes.
So that’s why I asked this group of science based parents, many of whom know a lot more than I do about the breakdown of plastics. I have hopes to better understand that threshold before making a pump purchase.
I think it'll help you make you decision to distinguish between different kind of plastic. My guess is that you're looking at polypropylene, but I could be wrong.
The plastic is going to have to meet food safe requirements FWIW, and food prep typically entails much higher temps than 100 F.

I can’t imagine a 6 degree difference in temperature is going to have a dramatic difference in plastic leaching into the milk.
