Bungee cord is the most readily used name for cord with a core that is composed of elastic strands coated in a woven sheath. Other names used for this type of rope are “shock cord” and “elastic cord”. Bungee is often spelt “bungie”. The elastic strands within the core of bungee cord are composed with natural rubber, manufactured rubber, or a configuration of both. The material used for the inner cord will largely vary depending on the intended use of the cord. The woven outer sheath can be composed from a variety of materials. Polyester cotton, polypropylene and nylon are all materials that can be potentially used for the outer sheath to protect the elastic core latex silk. The outer sheath also facilitates a uniform stretch through the entire length of the bungee cord. How Stretchy is Bungee Cord? Bungee cord can be manufactured to stretch to specific lengths and reach a particular amount of elongation. The amount of ‘elongation’ is identified as a percentage compared to the non-stretched length. For example, bungee cord that can be stretched to double its length would be described as having 100% elongation. What to consider when you’re buying bungee cord? Depending on the purpose of the bungee cord you are purchasing, and the amount you need it to stretch, the elongation rating of the bungee cord can be of primary importance. Generally, the thicker the bungee cord the stronger it will be. However, the thicker bungee cord is also generally harder to stretch, so be sure not to buy bungee cord that is so thick it can’t be stretched! It’s not just the elasticity of the bungee cord that matters, the material of the outer sheath is also massively important to its functionality. Your bungee cord will re-quire an outer sheath that can deal with the conditions it will be used in. If used in potentially inclement weather, you may need an outer sheath like polyester that is resistant to water.
