Traditional rubber stretch cord, commonly called shock cord or bungee, is well known and widely used throughout the industrial, domestic and recreational world. This stretch cord consists of many strands of latex rubber filaments, bound together under braided polypropylene or nylon fabric. When stretched, the braiding opens slightly and UV penetrates to the inner core perishing the fine rubber strands, eventually causing failure. Consequently, stretch cords when exposed to the elements need to be replaced regularly.
The marine environment is the harshest for stretch cord where is subjected to extremely high ultraviolet (UV) bombardment and exposure to the elements. The Cordall team, with thirty years boating experience behind them, was convinced that there must be a better product available. However, after searching the marketplace in vain they decided to develop a product of higher performance specifications themselves.
