In response to requests for a longer lengths of hybrid cord I have developed the SERE Go Cord 960. This is not a compromise and is one of my most advanced hybrid cords to date. It consists of an inner Braided Technora® core and an outer lightweight nylon kernmantle sheath (available in any GSA/US Contractor compliant 550 colour). The inner Technora® braid contains 16 strands, each with a tensile strength of 60lb!
It will initially be available lengths up to 100ft with the potential to increase to 150, 200, 250ft. The ends of the hybrid cord will be finished with a black permanent, flexible coating.
The diameter of the cord will be no greater than 550 paracord so it would be
possible to install 50ft of it on a DropLine Rapid Line Deployment System
These are the specs excluding the outer sheath:
Tensile strength = avg. 960lb (based on new lines tested under laboratory
conditions, and can vary by 10%).
Maximum Length = 250ft (76.2m).
Technora® is the brandname of the company Teijin.
- Fatigue Resistance: It has slightly higher resistance to flex fatigue than
Kevlar® and shows little loss of strength even during repeated abrasion, flexing and stretching.
- High Tensile Strength: Strong and light, weight for weight, Technora®. is 8 times stronger than steel and 3 times stronger than fiberglass, polyester or nylon yarns.
- Chemical Resistant: Highly resistant to acids, alkalis and organic
solvents; not vulnerable to damage caused by steam or sea water.
- Heat Resistant: Thermal decomposition threshold of 500°C, so Technora can
be used at 200°C for long periods. At 250°C, it maintains more than half of its room-temperature tensile strength.
The SERE Go Cord 960 will be released September 2012 and sold by the foot.
