Elastic Shock Cord

Elastic Shock Cord

Elastic shock cord, more commonly referred to as “bungee cord,” is a rope which has been manufactured to include a multi-strand rubber core. This rubber core serves to give the cord stretching ability, increased strength and greater durability than common rope. Elastic shock cords may stretch up to 125% of their original length under full strain. Size and load ratings may vary depending on the intended use of the cord.

In addition to its rubber core, elastic shock cord is available with a variety of coverings. Nylon, polypropylene, polyester and cotton are commonly used to cover and protect the inner elastic. Polypropylene cord coverings resist aging, deterioration from UV exposure, acid exposure, mildew and moisture. Nylon and polyester coverings are also resistant to aging, mildew, and acid and moisture exposure; however, both of these materials may be damaged by prolonged UV exposure. Cotton is strong, abrasion resistant and resistant to common solvents, but may not be as durable as synthetic coverings. Overall, polypropylene cord coverings offer the best durability and longest lifespan.

Elastic shock assemblies may be fashioned with hooks, rings and other custom hardware, depending on their intended use. Elastic shock cords and assemblies are utilized in a variety of industrial and commercial applications. Most commonly, these cords are used as tie-downs for cargo, for suspension purposes, in parachuting and the automotive industry. Elastic shock or “bungee” cords are useful and versatile enough to be used daily for multiple purposes in industry.
