Material Notes:
Property data below is for 1.5 denier fiber. Poly(p-phenylene-2,6-benzobisoxazole) (PBO) is a rigid-rod isotropic crystal polymer. Zylon is a new high performance fiber developed by TOYOBO using the latest material science and state of the art fiber technology. Zylon has superior tensile strength and modulus compared to p-Aramid fibers. It also has outstanding high flame resistance and thermal stability. Zylon shows excellent performance in such properties as creep, chemical resistance, cut/abrasion resistance and high temperature abrasion resistance, that far exceeds p-Aramid fibers. Zylon's moisture regain is low (0.6%) and it is dimensionally stable against humidity. Zylon is quite flexible and has a very soft hand, in spite of its extremely high mechanical properties. It can be processed into various product forms, such as continuous filament, staple fiber, spun yarn, woven and knitted fabrics, chopped fiber and pulp.Data provided by Toyobo Co., Ltd.
