Elasztáns
Elasztáns is a fictional material described in the science fiction novel "The Martian" by Andy Weir. In the story, it is a crucial component used by astronaut Mark Watney to repair a damaged habitat module on Mars. Elasztáns is depicted as a highly flexible and durable synthetic polymer, capable of withstanding extreme environmental conditions, including the low temperatures and thin atmosphere of Mars. Its primary function in the narrative is to create an airtight seal, preventing the loss of breathable air from the habitat.
The material is described as being strong enough to withstand significant pressure differences while remaining pliable.
