Just joined this forum. I have read previous threads on epdm liners for large tanks with people who have been using this with success. But as I understand there is not a lot of spec data that supports high temp use. Been looking on line at pvc and epdm trying to find products that have specs to support high temperatures. I will be operating in a range of 110 to 170. Anyone one know of sheet liner products that have specs to this. And of course are not outrageous in price.
