Mylar. Where did THAT come from? Oh, I know, you pulled it out of your arse like so much of your 'debunking' material.
Actually I got it from the Government Accounting Office. They published
The Roswell Report: Case Closed and it was on page 104. Look for the chemical name of the balloon material, which is called polyethylene. Mylar™ is the brand name for DuPont's polyethylene terephthalate. It was publicly available in the 1950s and therefore not a "common materials of the day" as Starman and VRob would like to believe. It's likely that there were other materials or gear on the balloons and payloads that a Cold War government would like to keep from being common knowledge -the kind of things that we wouldn't want Soviet analysts attempting to draw conclusions or inferences from. But the real question might be why you are interested in what might or might not be in my arse.
That the materials weren't "common of the day" is important, because it would explain why they weren't immediately recognized by the people who found them. If you came across a torn up Mylar balloon today, you would likely recognize it as the sort you'd find in Walmart, even if it didn't say "Happy Birthday" and sport an image of
My Little Pony. But in the late 1940s and early 1950s, this sort of material would have been as alien as if it came from another world.

Why not just state the balloons were made of 'secret carbon nanotubes' and make it sound real impressive.
Two reasons: 1) I don't know what a 'carbon nanotube' would be and, 2) the officially released information states that they were polyethylene, otherwise known as Mylar.
After all, neither Mylar nor carbon nanotubes existed in 1947.
Ahem:
Read this PDF and note how Mylar™ was
introduced to the public in the early 1950s. Roswell occurred in 1947. Moreover, the GAO states in its own report that the material was polyethylene (a.k.a. Mylar™ ).

It takes about 60 seconds on google to find out
... that the internet is
popular culture, not necessarily the end all, be all of information. Look past the woo-woo sites into the primary sources for a change. i.e. DuPont, Inc. and the GAO. Oh... yeah, you don't trust the government. Oh well.
The problem with rubber balloons was that they
expanded as the gas expanded, thus bursting as they gained altitude. The polyethylene/Mylar balloons didn't. Altitude was what was important, since the goal was to gain as high an altitude as possible. Perhaps the earlier balloons were, indeed, constructed of neoprene, prompting the use of the new material of Mylar. But let's not overlook the fact that Roswell is near the White Sands Proving Grounds, just where you would expect such operations to occur. Perhaps the
Case Closed reference (p. 104) is in regard only to Operation High Dive, but the difference in time is negligible and because of the altitudes Operation Mogul was attempting to achieve, just neoprene wasn't going to work. The Operation Mogul balloon series may have had a combination of neoprene and polyethylene since they used a "string" of balloons and the Mylar™ balloons weren't filled to capacity in order to allow expansion of the gas. The neoprene balloons may have been used to provide initial lift.
There are a lot of possibilities regarding Project Mogul and Project High Dive as far as operationally how they were done and the appearance of the debris they left. What is certain is that these types of missions were conducted. First, we have photographic record as well as some operational records as released by the Department of Defense, GAO, et al, which depict these operations. Second, they are exactly the
kind of operations that would have been necessary in a post-WWII, Cold War United States in order to gain intelligence and improve flight technologies.
That people perpetuate the
mythology surrounding Roswell isn't surprising. Humans live for a good myth it seems.
