foam companies have an incredibly shady history in California -- my dad was the customer of one in the 80s, the owner had hired an incompetent forklift worker and a huge chemical spill proceeded.

I remember my dad getting a phone call in the middle of the night from the owner 20+ years ago : " X, you've always been a great customer of mine, if you want or need anything I have at the shop then you're free to come get it tonight."

We got in the car and got sheet after sheet of urethane foams, we were using it for aerospace and bicycle stuff at the time, as well as some small hand tools and miscellaneous stuff that he offered us.

The facility was chained and barred that next morning

A week later the entire facility burned down

A month later people from the EPA started contacting the owners' business partners and larger contracts; turns out that after the fire there was some extensive soil testing, and the owner and anyone involved was nowhere to be found to be asked to pay for the extensive environment rehabilitation to deal with (among other things, i'm sure) the huge chemical spill.

We never heard from the owner again. I don't know whether or not the fire was an accident , but even as a kid I just presumed it was a failed fraudulent cover-up attempt or insurance grab; but I guess we'll never properly know.

It wouldn't surprise me in the least bit if Clark Foams shut down as a preventative measure to avoid a huge EPA hassle for the owner; making foam is a nasty business, and it's expensive to do it by-the-book.
