Plastic vs Stainless Mash Tun

[RM-MN]

what about plastic seeping into mash at such temperatures?


I know coolers have thicker plastic inside than plastic water bottles but I am sure there must be some seepage at 150F for an hour long mash.

Study Details

• 16 plastic water bottles were exposed to different temperatures: 39°F (4°C), 77°F (25°C), and 158°F (70°C).
• Levels of BPA and antimony were checked after one, two, and four weeks.
• Antimony concentrations in the water from plastic water-bottles averaged 3.18 ng/L at 39.2°F (4°C), and 6.88ng/L at 77°F (25°C).
• At 158°F (70°C) (about the temperature in a car on a hot summer day), levels of antimony in water increased significantly to 38.5 ng /L.
• Levels of antimony in one of the sixteen water bottles increased to 2604 ng/L.

There are lots of different plastics used for different purposes. Your water bottle study is from one type of plastic but coolers use a completely different plastic so your study does not apply. Try to find a study that uses the same type of plastic.

And has anyone mashed for 1, 2 or 4 weeks?
