Several possibilities are British slang for India rubber may have been bungee or bungie. Another possibility was earasers made of a type of rubber for removing pencil marks from paper have been referred to as India-bungie. The Oxford English Dictionary says the phrase bungee-launching was used in referring to using elasticized cord to launch gliders.
Bungee cord or shock cord is made with either natural or synthetic rubber. Each material has advantages and disadvantages. Natural rubber aka latex rubber has the ability to extend and then come back to its original shape.
It also has a high tensile strength which allows it to extend under a load without breaking. However, natural rubber does not resist air and light well. Synthetic rubbers like neoprene resist natural elements like sun and air but don't as well as natural rubber in returning to its original shape and have less tensile strength. These cords are found in virtually every hardware store. They are sold individually, in bundles and in tubs containing multi size and lengths.
Bungee cords usually have hooks attached to them. Bungee cord can be purchased in bulk without the hooks. My brother in law is a truck driver. He uses bungee cord to secure tarps when hauling flatbed loads. No hooks required for him, he has a way strapping his tarps without them. Bungee cord is good for business, so says the eye doctor. It is responsible for a lot of eye injuries. I believe this comes mostly from over extension extending or pulling the cord farther than it is supposed to stretch.
Bungee cord can have longer or shorter elongation ratings. Used properly you shouldn't have a problem. Full information on the military specifications we meet with our elastic cords can be found here. 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. Bungee cord is now used in hundreds of different ways including bungee jumping off of cliffs, bridges, or buildings. They are mainly used as a way of storing and securing items in households, vehicles, or in workplaces. Synthetic rubber is also produced to better resist the effects that ultraviolet radiation can cause.
Strands of rubber are first prepared by heating and turning them into long ribbons that are then cooled and put into coils for either distributing to a manufacturer or for being covered in a nylon or other kind of material braid. While each of the strands are being uncoiled for the braid, they are powdered to prevent them from sticking together when the cord is used outside or in hotter temperatures. Bungee cord is the most common name for a cord that has an internal core composed of elastic strands that are covered by a woven sheath.
Bungee cords have several names, which includes:. Shock cords are constructed with an elastic inner core made from either synthetic rubber, natural rubber, or a blend of both. The inner core material and type determine the character traits of final products. Below, we will highlight a small list of three essential considerations to make when shopping.
