Spectra parachute lines. Spectra is ultra-high-molecular-weight polyethylene.

Spectra parachute lines. ” Feb 1, 2021 · Spectra line has a limited life and will generally need replacing any where from 300-600 jumps for 500lb line and 500-1000 jumps for 725lb line. It is a low-bulk, low-drag line that wears very well and is very hard to break. This is what we mean when we say a canopy is “out of trim. Oct 1, 2020 · To illustrate how your lines lose strength over time, we took some linesets at various stages of life and submitted them to a series of tensile tests. . Sep 25, 2019 · Spectra and Vectran lines are comparable in terms of weight and diameter, but Spectra wears better long term, absorbs less moisture, furs & frays less over time, and is generally more durable (when pitted against UV exposure, bending tests, and even Velcro-abuse, Spectra wins hands-down). However, it is not very dimensionally stable because it is susceptible to shrinking when heat is applied. May 16, 2012 · Spectra: This is the most common line type in the skydiving market today, and for good reason. Spectra is ultra-high-molecular-weight polyethylene. Sep 25, 2019 · Spectra and Vectran lines are comparable in terms of weight and diameter, but Spectra wears better long term, absorbs less moisture, furs & frays less over time, and is generally more durable (when pitted against UV exposure, bending tests, and even Velcro-abuse, Spectra wins hands-down). Vectran is our preferred and most commonly used line type, standard on all our canopies. It is a very strong line and doesn't stretch or shrink easily, so it holds its trim well. Vectran is an aromatic polyester while HMA is a aromatic polyamide. Mar 12, 2025 · After several hundred jumps, some of the lines may be a few inches shorter than they were when the canopy was new. Note: your canopy may need re-lining sooner as a result of being out of trim (refer above). In today's world, parachutes are lined with mainly four different types of materials: Dacron, Spectra, Vectran, and Technora (High Modulus Aramid [HMA]). The results are shown on each photo as a percentage of strength loss. It wears more easily than Spectra, especially in hot, dry or desert-like environments. agfafk xhl bcgde yjsfg uhhk vbt smbfh vwfvb vdx ybxchrjhm
