Ldpd vs hdpd buckets

Postby goinbroke2 » Wed Apr 12, 2017 1:29 pm

So I went to buy another hdpd garbage can to ferment in and can't find one now! :evil:
Buckets yes, but nothing bigger than 20 or 30 litre size. So, as long as I don't dump boiling liquid in it, can I use ld as opposed to HD?
Far as I can find it has to do with temp handling.

Thanks
Numerous 57L kegs, some propane, one 220v electric with stilldragon controller. Keggle for all-Grain, two pot still tops for whisky, a 3" reflux with deflag for vodka. Coming up, a 4" perf plate column. Life is short, make whisky and drag race!

I am no expert but I think you mean LDPE vs HDPE. Along with what you have said about high temperatures I think the LDPE is prone to loss of strength when exposured to light and oxygen thus more prone to deform in shape.

Most of the links I found say keep with the white LDPE buckets to prevent dye leaching, and only for low alcohol (ferments).

I use a brute 20 gallon garbage can as my fermenter. I used to use it for mashing at high temps until I found out that LDPE is no good above 176 or so. It would get soft but not too bad. I now use the can as a fermenter for cold sugar washes and masehes done in my cooler (off grain ferments). I wouldn't worry about dumping boiling water in it as long as it was going to be tempered down with cold water (boiled inverted sugar). Make sure there's some water in the bucket beforehand and it'll be fine.

Lol, yeah ldpe I guess that's why I couldn't find anything when I used the search. Lol.

I keep it at 155 when doing all grain so I guess it should be ok then. Saw those 170 litre ones on sale the other day but didn't get one, now I'll go back and see if they're still on sale.

Thanks for the responses guys.
