This extreme conditions shock cord has the highest U.V. and abrasion resistance of our range, which makes it a perfect fit for marine or all outside heavy work.

The best option for extreme conditions; the PES elastic cord has an inner core with added U.V. agents and a PES braided cover that protects the rubber from ultra violet radiations. This shock cord is perfectly suited for outdoor uses combined with, for example, sun protection for agriculture or aquaculture. 

Abrasion resistance is one of the W70 PES shock cord main features. Designed to be used in marine conditions, it can suffer high friction without decaying.


The inner core unique feature of W70 PES keeps the shock cord round when cut. The PES outer covering allows for a soft touch and an easy to bend shock cord perfect for making knots on boats or for general storage.


Good pulling – return force is a must when you use shock cords on a boat or in industrial fields where high strengths are needed and Monoflex PES shock cord offers just that.


When it comes to strength at breaking point, W70 has the best results in our range. High strength at break insures safety when using the PES elastic cord. The W70 will be perfect to maintain material where difficult weather conditions and high strains can be met.
