igloo beverage cooler. heat capacity

I see that many brewers use teh igloo beverage coolers as mashtun. Im thinking about getting a 10gallion(yellow and red) for myself. but efter reading on the sellers page on ebay that it can have max. 60 degrees celsius fluids inside. mashing goes up to 70-80 degrees in the end. Is this a problem? safe to use?

cheers

Hi ... Finland!! Welcome! Er, I have 2 of those yellow 10 gallon igloo's with red tops and I routinely pour in almost boiling water 204F to strike my grain bed so it lands at 168F... and I'll say this, Yooper told me it was ok ... seriously though the thread has been on here before and it is safe to mash in them. I only heard one person say that putting boiling water in the igloo caused the inner and outer parts to delaminate. So stay below boiling, but 170-180 no worries.

Here is the thread:

Thanks for your answer dude even though I´m lazy I did try to do a forum search but didn´t find that thread, so thanks!
I might as well Order that Igloo from ze germanz then.
cheers

Ya, if it is still available would be very useful for your brewing
