Spectra webbing age dyneema Dyneema® and Spectra® are different brand names for the same very strong fiber (chemically Ultra -High Molecular Weight Polyethylene - referred to below as HMPE). . This remarkably durable material is one of the world’s strongest and lightest fibers. Feb 9, 2011 · Dyneema aka Amsteel aka Spectra are all spun cords made of ultra-high molecular weight polyethylene. Functionally, Dyneema slings may appear to have lower wear resistance than nylon and/or age quicker than nylon uhmwpe: spectra®, dyneema® OTEX HIGH-PERFORMANCE UHMWPE (SPECTRA® OR DYNEEMA®) WEBBING, TAPES, & TUBES OTEX® high-performance UHMWPE Narrow Textiles are a critical component for many life and property protecting applications for such demanding sectors as aerospace, fall protection, crane rigging, flood protection, and more. We hope to change this with a new long-term test series starting this summer. Spectra ® / Dyneema ® are Ultra-High Molecular Weight Polyethylene fibers known for their high strength and durability. This fiber has very attractive properties: extremely strong (15 times stronger than steel fiber of the same weight) and low stretch for its weight, Jul 14, 2008 · Honeywell developed a product identical in chemical structure, which is sold under the brand name Spectra. It floats, making it great for painters, tow ropes, and anything you don't want fouled up in your prop. We created a more specific UHMWPE (=Dyneema/Spectra) webbing category from which our database does not (yet) allow to make precise recommendations for lifetime, due to a small amount of datapoints that fit the category. A manufactured fiber made from ultra-high molecular weight polyethylene. I believe 60, 75, 78, etc all refer to the strength to weight ratios when this material is spun to create oriented-strand yarns. Sep 4, 2010 · Dyneema has a 10x higher tensile strength than steel when you compare equal masses of the materials - not if you compare a skinny climbing sling to a large girder or I-beam. At the same strength as steel wire, its 75% lighter, suffers only from UV corrosion, and is easy to handle. The same principle applies when comparing climbing slings.
