Poly (p-phenylene-2,6-benzobisoxazole) (PBO) is a rigid-rod isotropic crystal polymer. PBO fibre is a high performance fibre developed by TOYOBO (Japan) and has superior tensile strength and modulus to Aramid fibres, such as Kevlar, Technora and Twaron. It also has outstanding high flame resistance and thermal stability among organic fibres. PBO fibre shows excellent performance, in such properties as creep, chemical resistance, cut/abrasion resistance, and high temperature abrasion resistance - far exceeding other Aramid fibres.
PBO fibre's moisture regain is low (0.6%) and it is dimensionally stable against humidity. PBO fibre is quite flexible and has very soft hand, in spite of its extremely high mechanical properties.
Over the past ten years Future Fibres has pioneered the use of PBO for yacht rigging and has proven it to provide remarkable performance and longevity. PBO's properties deliver the lightest, smallest cables available on the market today.
