I recently purchased some 1/4" thick foam to use as padding for thigh braces on my fiberglass Impex Assateague. I had a lot more trouble finding something locally than I thought I should, so I ended up buying online from here:
The link above is to the product I ended up getting. I selected 4lb density, and 1/4" thick, white. What I received didn’t match up with what I think of as “Minicell” foam. The bubbles (cells) are much larger and the surface is not near as smooth.
When I tried to figure out what the density of “standard” Minicell foam is, I came across this:
Which claims Minicell is 2lb density.
I’m going to use the foam I received, as I think it will work ok (perhaps even more durable) for the application. Time will tell if it holds up, and if it doesn’t then I just replace it with something else. If I get more than a few years from it I’m happy enough.
But it still bugs me. So, is it me, or would anyone else think that a larger number for density would indicate fewer/smaller bubbles and less air space? Do I have this totally wrong, or where did I mess up when trying to get the right thing?
