Is "Cellfoam 88" and "Sintra" the same thing?

[Kmot]

I see Midwest Products Co sells a new product called Cellfoam 88. I was wondering if anyone knew if it is the same type of material as Sintra?

The Midwest Cellfoam is another version of the closed cell PVC originally trademarked as Sintra. Sintra was one of the earlier closed cell expanded PVC boards made and trademarked.

As usually happens, the first type of a new product quickly becomes a "generic" name for similar products made by rival companies. Other examples are:
Crescent Wrench - not every open end adjustable wrench is made by the Crescent Tool Co.
Mr. Coffee
Kleenex
Skilsaw - even if it's cordless and made by DeWalt?
Chadburn - one company that makes the classic engine order telegraph

You can buy Sintra pretty cheaply from a sign shop. Just ask for their scrap pieces. These are usually good sized pieces that are just too small for a sign. One sign maker gave me his small pieces, another charged $9.00 for a 2 ft sq piece of 5 MM.

Bad Bob! No mug of coffee for you, now go clean the head!

Cellfoam 88 is the lightweight stuff that foamie planes and trays for hamburger in the supermarket are made from.
Midwest's "Sintra" is referred to as "PVC Foam" on their website.

I have yet to try the Sintra in a project, so can't say if it's good or bad.

My material of choice is and has been sheet styrene, usually .060 thickness,
chemically welded with MEK. (methylethyl ketone)

Bad stuff to be sure. I have used it in the past laced with enough styrene chips to make a working slurry. Not only does it weld and dry fast but it is almost invisible when dry. The down side is that it is a proven Carcinogen and needs lots of moving air when being used.

That answers my question. Thank you.

I stand corrected. Captain of the Head reports that the head is secured until after the CO's Materiel Inspection. All hands have to use the port a potty on the pier.
