Black Shock Cord

Elastic shock cord, or bungee cord, has a multi-stranded rubber core covered by a synthetic or cotton jacket. A standard bungee cord has a stretch factor of 100 to 125 percent when stretched to its ultimate break. The assemblies can be made with hooks, terminal fasteners, loops, rings, and other hardware. Other stretch factors are available in custom constructions. We offer this cord on spools, in custom cut lengths, or made into assemblies. Colors Offered For Elastic Cords Phoenix Rope & Cordage offers bungee cord in a variety of different colors, and some of our most popular colors are: Yellow Elastic Cord Blue Elastic Cord Black Elastic Cord Green Elastic Cord Red Elastic Cord Pink Elastic Cord Materials Used in Bungee Cords Bungee Cords are typically made using synthetic or natural rubber. The elastic part of the cord is covered by a braided material, and this braided material is typically made up of either nylon, polypropylene, polyester, or cotton. These fabrics have different advantages depending on the application of the bungee cord. The polypropylene material is better suited for outdoor use, and the nylon bungee cord performs well in marine applications. Nylon performs well in marine-based applications because it absorbs moisture better than cotton and polypropylene. Diameter Put-up Approx.
