Bummer, I wonder if more companies will switch to whoever makes the Spectra branded fibers with this. |

UHMWPE is not the only high-strength material out there. Other potentially plausible fibers include Vectran, Technora, Twaron and maybe Certran. Vectran and Technora are already used in the manufacturer of ropes for safety-critical applications. |

Since most of the major rope manufacturers are already using Dyneema, Technora, Vectran, Kevlar and others in their product range I´m suprised they haven´t mentioned it to their climbing textiles division. |

How else will they keep their over-paid "athletes" in business class? We pay $10 for dental floss when an entire airplane cargo net of the stuff goes for a few hundred dollars. |

Do you have a resource with some information on these? I only ask out of curiosity - I'd like to learn more about them. |

Some yachting supplier websites as well, as tech fiber cords are quite popular with the high end and competitive racing side of things due to higher strength/lower diameter/lower weight.

what the hell is 'safety-critical'? |

my TR static line is a spinnaker halyard from a J45, free dyneema baby! |

Bluewater makes a Vectran sling called the Titan and it is less expensive than many Dyneema slings of the same length. I think Mountain Tools makes a Vectran sling that is competitively priced as well. BSM, one of the largest webbing mills in the United States, makes Dyneema slings for a few climbing equipment companies. I had a nice chat with them awhile back. At first, they had significant trouble getting Dyneema slings to pass the UIAA certification because the pin diameter the UIAA uses is relatively small (to resemble a carbiner). It was not without much R&D effort that they were able to develop the perfect weave and shape to allow the sling to pass the certification test without costing too much from excess material. However, prior to them developing a finished product, it was questioned if Dyneema was the right choice. Five years ago, high-tech fivers were almost non-existent in the slackining world. Now, numerous high tech fivers are used to weave 1" webbing for highlining and slacklining. All I am saying is that numerous options exist, and possibly with the right R&D, it is fully plausible that we could start making slings with a new material. |

you would have to get any new materials recertified and tested ... |

switch to safety-critical cannabis |

D.Buffum wrote:I don't know this for certain, but I suspect the cost of the fibers/materials is a pretty minor expense in the overall cost of a sling. Overhead for operating the manufacturing is probably far greater. And then there's testing and licensing to ensure UIAA compliance.That is a good point. Webbing manufacturing is very slow and labor intensive. I recall a price quote for some Vectran webbing for a personal project. Ordering a 400' prototype was only slightly less expensive than ordering 1,000' because the amount of time to set up the machine was the same. |

A rough calculation gives about 60c or less worth of Dyneema in a 60cm sling. |
