Often refered to as bungee cords. Our highly elastic shock cords are made with a polyester braided cover to protect the latex rubber core. Polyester is very UV and abrasion resistant so it will help to provide a longer lasting product than cords with polypropylene or nylon covers. In general you can expect a shockcord to stretch to up to twice its original length at maximum tension. Rubber deteriorates over time but you should expect 5-10 years useful life from our bungee lines. Technical Specification: 100% natural latex rubber core with a braided polyester cover. 3-4 mm - 12 plait, 5-6 mm - 16 plait, 7-10 mm 24 plait and 12 mm 32 plait.
