Plastic Mash Tun Safety
« on: September 09, 2015, 01:17:48 PM »
Does anyone have any current information/data on the safety of using plastic coolers as a mash tun? I have read posts on this topic, but they are a few years old.  Igloo website says not to use coolers with hot liquids.  Many of the homebrew online stores are selling their own versions of all-grain systems utilizing coolers.  I have contacted two of them and they do not seem to have data on the construction materials.  Maybe I am being overly concerned, but if I am making the effort to make my own beer at home, I don't want to increase exposure to any toxins as a result.  If anyone has any updated information, I would gladly appreciate it.
Thank you.

In most cases of coolers we're talking about HDPE. Everything I've seen about HDPE is that it can have continuous use at temperatures into the 200s °F. Since I never get to even 200F in mine I've stopped looking for any further information at that point.

Listen to the presentation from this year's NHC on Homebrew toxicology, as well as the podcasts on the same topic on Basic Brewing Radio. The basic gist is that there is very little concern with exposure to anything toxic in plastic coolers, even at hot temperature. I'd just give it one or two rinses with hot water prior to use. Any residues that are remaining after manufacturing are water soluble and will rinse out easily.

I think the inside of a lot of coolers are polypropylene, which is food safe and generally tolerant of heat.

The igloo cooler warning seems to be related to the insulation inside.  I've had a round sparge water cooler warp due to adding boiling water, but never an issue with mashing.

"The beverage coolers are not recommended for use with hot liquids. The hot
liquid can cause the insulation in the cooler to expand causing the liner or
outside body to crack. If you plan on using hot liquids this will void your 1
year warranty. "

I don't know about other manufacturers, but the interior liners of Igloo coolers are made of FDA-grade polypropylene.

There is an "infectious dose" that gets discussed in environmental engineering.  Every time you are in a public restroom and someone flushes a stall toilet there is no helping that you will inhale fecal matter; however, it simply isn't enough to make you sick.

There was a Mythbusters that showed it is all over your bathroom at home too.
