Vectran

The wispy, hair-like fibers tend to fray, to easily acquire dirt, and to readily entangle in hook-and-loop fasteners, from which they must sometimes then be cut or (when possible) torn.

[2] If used without protective coatings, Vectran has low resistance to UV degradation, and should not be used long-term in outdoor environments.

It is used as one of the layers in the softgoods structure of NASA's Extravehicular Mobility Unit (spacesuit) designed and manufactured by ILC Dover and was the fabric used for all of the airbag landings on Mars: Mars Pathfinder in 1997[3] and on the twin Mars Exploration Rovers Spirit and Opportunity missions in 2004, also designed and manufactured by ILC Dover .

[5] Vectran is a key component of a line of inflatable spacecraft developed by Bigelow Aerospace,[6] not only on two stations which are in orbit[7][8] but also the Bigelow Expandable Activity Module which NASA is testing for its radiation shielding and thermal control capabilities.

[9] The United States Department of Homeland Security is sponsoring development of an inflatable plug made of Vectran to prevent flooding in New York City Subway tunnels and for other tunnels in New York City, as it is strong but relatively inexpensive, and not edible for rats.
