Vectran vs dyneema reddit Dyneema and Vectran are both available in several grades, but the common Dyneema SK75 has a tenacity of about 43 grams per denier, and Vectran HT has a tenacity of about 29 grams per denier (in the same neighborhood as para aramids like Technora, Twaron, and Kevlar). Kevlar. The Dyneema, Spectra, and Vectran lines on this page are Single Braids. Feb 20, 2016 · Dyneema is the one that is stronger but sensitive to heat. Dyneemahas a higher tensile strength and strength-to-weight ratio than Vectran. UHMWPE fibers have an extremely high strength-to-weight ratio, but a very low melting point (266-277F) compared to other common rope materials. Vectran is slightly weaker than Dyneema® fiber, but does not suffer from creep (elongation under continuous high load). Now that we’ve looked at the individual properties of Vectran and Kevlar let’s compare the two materials side-by-side. 9oz/yd²) - $, quite soft, seems pretty tough, moderately waterproof, could probably be seamsealed PU1000/DWR Woven Melange Dyneema (237g/m² or 7oz/yd²) - $$$, interesting fabric, strong and totally abrasion resistant, quite soft and mellow, not as waterproof as other fabrics, difficult/impossible Sep 25, 2019 · Vectran, by comparison, absorbs enough water to where damp hairy lines can be an issue after landing in wet grass. 2.
