If you are not aware, 1e-11 torr means just 1 bar pressure inside suit. Even less, because even on passenger planes internal pressure is lowered to 0.8 bar on regular flights. Using oxygen only you could safely lower pressre to 0.3 bar. Nothing exceptional at all. You literally could make space suit from bike helmet, some plastic PPE, boots and gloves. Some hacking to make it air tight together and you are in business. You will have more problems with dissipating heat your body produce than with that 1e-11 torr vacuum.
Why the hell that "1e-11 torr" is used in all that space memes as something extreme or very dangerous? It is just 1 bar pressure difference with atmospheric pressure on the Earth surface. On the passenger plane cruise altitude of 10km pressure is 0.25 bar, so difference with pressure on the Earth surface is 0.75 bar. Since when 0.75 bar pressure difference is something very usual thing nobody really care about flying in passenger plane, but 1 bar pressure difference is something exceptional?
It is much harder to make underwater suit for 100 meter depth, because pressure difference is 10 bar.
As for the price - what government institution do not laundering tax money today?
it is the material's resistance to degradation from the vacuum itself.
Rare materials degrade in vacuum at all. Some closed-cavities styrofoam, and something like with gas inside. Few materials that have to contain liquid and volatile substances to keep specific properties like decorative water-keeping jelly balls for flowerpots. Hardly you will find anything in that list that somebody will ever choose for space suit.
UV light and temperatures range are magnitude orders more important in question of material degradation in space, but they are not very different from those on Earth surface.
Vaccum is absolutely nothing, in literal and metaphoric sense for materials. It is not even in the top 10 things harmful for human without any protection. Here on Earth surface we have much more dangerous things without any space wonders.
That attempts to use vacuum as some scarecrow for ignorant audience are just stupid.
Only thing that is interesting to explore about space vacuum is who and for what purpose pictured space vacuum as something instantly deadly and severely destructive in all that mass media production, when all real properties of vacuum was perfectly known for arond two centuries.
Of course most RTV sealers will lose mass, regardless of vacuum or normal pressure, because thinner is added to most Room-Temperature Vulcanisation sealers to make their application easier and provide better adhesion. Thinner will diffuse to the surface and evapourate with time, faster in vacuum or at high temperatures, as any volatile liquids do.
This mass loss will not anyhow harm RTV sealer at all. But it could contaminate vacuum in some sensitive equipment and even damage sensors or poison some ion trap or whatever inside vacuum chamber sealed with this sealer. For such purposes thiinnerless 2k RTV sealers manufactured. But they are harder to apply and more expensive. There is no any sense to use them for sealing large surfaces for space, because nobody cares about contaminating outer space with few grams of thinner molecules.
Funny, you already tried to push exactly same crap here earlier. Somebody decided that everybody forgot about it and it is time for next round of pushing narrative?
There is no vacuum chamber on earth capable of testing suits at those vacuum levels.
There is no need to do that at all. "vacuum level" of 1e-11 torr is not noticeably different from vacuum of 0.1 torr from the material strength science point of view.
It is like difference between 99.9999 purity gold bar and 99.99999999999999 purity gold bar. You will not find any measureable difference in mechanical properties of that gold bars.
Traditional rubber type seals do not work at those vacuum levels.
Bullshit. Anything more or less elastic will perfectly work at this levels for containig atmosphere.
Problems with high vacuum is in no way connected with any imaginary dectructive properties of high vacuum. Problems about keeping high vacuum pure enough in some applications like electron microscopy, ion spectroscopy and so on. It is about protection of vacuum, not about any damage to rubber.
Rubber, silicone and other elastic gaskets usualy made using lubricants or thinners. In any vacuum, just like in regualr air this lubricants or thinners will evapourate. It absolutely does not matter if it happen in space, but that lubricant or thinner molecules in some high vacuum precision device could ruin the day.
For space suits, spacecrafts and all that stuff vacuum in space is just 1 bar pressure difference and nothing more. Regardless of how low torr value you have.
What's funny is that we are told that, if not for the space suit containing perfect vacuum of air, the human's blood vessels would burst. And yet your fake astronauts look like they are going to ride dirt bikes through a swamp. Fake and gay.

According to NASA's own documents, the RTV used to seal the windows of the spacecraft loses mass under only 10^-6 tor vacuum:

Tighty whiteys worn over the top would complete the ensemble
Man those boots are a strange choice
NASA is so fucking gay lmao.

This issue really brings out the trolls because it is a hard problem unresolved by NASA.

Bicyle tire seals withstand a greater pressure difference than that.
You are full of shit.

Never seen a bike helmet like this.

That's a completely different helmet.
Did you just search for "white motorbike helmet"?
What's funny is that we are told that, if not for the space suit containing perfect vacuum of air, the human's blood vessels would burst. And yet your fake astronauts look like they are going to ride dirt bikes through a swamp. Fake and gay.
That sentence makes no sense at all. The suits contain atmosphere, not vacuum.
If you think that a pressure difference of 1atm is some technically insurmountable obstacle, how do you explain car tires?
Can you please post a link where I can buy that bike helmet, gloves and boots?
