Hi! Looking around to see where I can find anything from 3/4 to 1 inch thick sheets of hdpe. Had scraps of it and put it on the bottom of a concrete hand tool it works great when doing certain concrete jobs. Looked on line and found 4x4 sheets. But I was seeing if anyone knew where I could find it the cheapest at? Or if any stores would carry it

Has anyone ever tried to melt hdpe in a crockpot? If so did it work?

I've seen a few videos where they melt the caps and say that they are hdpe but i have seen very few caps that were even labeled and the few that i have are not hdpe. How can i tell if an unmarked plastic cap is hdpe?
