POLYESTERPMI Polyester ropes are great for use by experienced technicians in applications where low stretchis required. Although extra precautions must be taken when using a polyester rope in rescue systems,there are also many benefits when used in the correct application.1) Polyester retains a high tensile strength even when wet.2) Slightly more resistant than nylon to most acids.3) Melting point is about 480 0 .4) Highly abrasion resistant.All PMI ropes that incorporate polyester in some way have an X pattern on the sheath, while nylon-onlymodels feature the typical “barber pole” design.OPTIMIZERope sag due to elongation (stretch) is often an issue with highlines. Too much sag can make it difficult to clear obstacles. Excessive sag in a horizontalhighline will also increase the amount of work required to manage a load across the span. Polyester core kernmantle ropes help reduce this sag due totheir much lower elongation under load. PMI’s Talon and Isostatic polyester core ropes are a great choice as track lines in a highline operation. Choosinga low elongation rope will make it easier to tighten the highline and less sag will be induced in the system as it is loaded. Keep in mind, however,that less catenary in the system will result in higher forces at the anchors - a situation that can easily be monitored by incorporating load cells into yoursystem. Note also that the system will be much less forgiving of shock loading and great care should be taken to prevent dynamic loading events.MEETING THE STANDARDSPMI Isostatic Ropes meet NFPA 1983 and CI 1801, but provide lower elongation under load and thus lower shock absorbing ability than PMI ClassicStatic ropes. Choose PMI Isostatic for rigging highlines and long hauls where rope elongation can be an issue, but always keep in mind the lower shockabsorbing ability.SOLUTIONSWe recommend using Isostatic with the heightec-PMI TM products since it has a somewhat softer hand than our Classic Static rope. All of the heightec-PMI TM Rescue Systems on pg. 86-89 come with PMI 11.5 mm Isostatic for your convenience.PMI TALONPMI Talon is the best of both worlds for experienced rope users. This rope combines the hand andhigher friction that you’re accustomed to from PMI Classic nylon ropes with virtually no elongation.Key Features:NFPA Certified . 16 carrier construction . 6,6 nylon sheath .
