Finding the right foam

Hey all, 
I'm trying to build blocks out of foam that need to be anti static foam because it is going to interact with a tablet touch screen It needs to be about 1in thick. I was planning on using polyethylene foam but I wasn't sure about where to go to buy it could anyone help? I'm open to suggestions about better foam choices as well but my budget isn't very large. Thanks!

Do you mean the pink stuff, or the black stuff ?

A couple of ideas:
I don't know the size of your blocks , so this may all be impractcle.
1) Lots of discarded luggage has foam padding in it to protect laptops etc.
2) same with furniture cussions
4) Thrifyt sho[ps have camping pads and yoga pads
5) .Expandable foam in a can ( Great Stuff ) can create foam blocks of varying densities. Stuff is tricky to work with.
Good Luck

How much foam do you need? (i.e dimensions)

Last time I went looking for the stuff, I almost passed out when I saw the prices. o_0
