What Materials are in Bungee Cords


Basic Bungee Cord Structure

The Basic structure of a Bungee Cord consist of rubber inner core, sometimes has a cloth material jacket also known as a weave or braid. The braided material originally is produced white and a dye is added to make the many different colors available. The rubber core can be made with a few types of materials & even scrap rubber materials to reduce cost in other countries. The best material is a natural material called latex. In its natural form it is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”. The latex is mixed with other materials like polymers of the organic compound isoprene to create rubbers.

Q & A


Question : How Far Does a Bungee Cord Stretch?

Answer :
Most Bungee Cords Have a Maximum Stretch 90% to 120%,
Not Recommended to Exceed 50% of Relaxed Length.

Bungee Cords Can Last for Years, But the Sun is a Bungee Cords Biggest Enemy.

Reason: Bungee Cord has UV Protection, But the Sun Still Burns Threw It. First you will see Discoloration, After that the Cord will start to Look & Feel Rough to the Touch.
