Kuraray America Inc. (Fort Mill, S.C.) has introduced Vectran HT, a high-tenacity thermotropic liquid crystalline polymer (TLCP) fiber that is being offered as an alternative to aramid fibers. Solution-dyed Vectran HT fibers are available in several new colors, such as blue, green and orange, and provide enhanced UV resistance, colorfastness and strength. The HT fibers also will be manufactured in finer filaments and offered as staple fibers for creating blended yarns. The fibers feature mechanical properties and chemical attributes that reportedly make them suitable for aerospace, composite, inflatable, rope and cable, heavy marine and industrial applications. Mechanically, the fibers are said to be three to five times stronger than polyester fibers and as much as 20 percent stronger than aramid fibers. HT is a high-modulus fiber designed to exhibit low creep under load. When compared with other high-modulus fibers, the material, says the company, ranks high in abrasion resistance, flex-fatigue endurance and dimensional stability as well as chemical and heat resistance.
