550 Cord Nylon Parachute Cord 400 Yards

Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is useful for many other tasks and is now used as a general purpose utility cord by both military personnel and civilians. This versatile cord was even used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space Telescope.[1] The braided sheath has a high number of interwoven strands for its size, giving it a relatively smooth texture. The all-nylon construction makes paracord fairly elastic. Current technical standards for the manufacture of cord for use in parachutes are published by the Parachute Industry Association. The US military MIL-C-5040H standard required the material to be nylon.[2] Similar styles of cord are manufactured with other materials such as polyester.[3]
