Vectran ® exhibits no creep even at high temperatures loaded to 50% of its breaking strain. Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. With very good performance characteristics often come high prices. Rocket-Fibers is a provider of high-performance fibers and textile products at quantities that makes sense for customers of all markets and applications. Kevlar is costly and worth considering for racing sailboats and offshore cruisers. The antenna was inflated by the crew and maintained its shape for a complete orbit, performing as expected. Additional drawbacks of Kevlar include poor UV resistance (Kevlar loses strength roughly twice as quickly in sunlight as polyester and, when affected, the gold Kevlar fibers turn brown) and rapid loss of strength with flexing, folding and flogging. Tubeless tires are the in thing at the moment because tubeless construction take material away (aka the the tube) and allows lower pressures, which results in a more supple tire, that has more traction and often less rolling resistance. Comparison of Properties of Various Yarn Materials Material Density (g/cm3) Tensile Strength (GPa) Tensile Dyneema | Vectran | Kevlar + At Right Rope, we offer dyneema rope that's stronger than steel.
