PBO (Zylon) The high performance fibre
Type : HM, E-modulus: ca. 245 GPa, Tensile strength: ca. 5,900 MPa, Density: 1.34 g/cm3
PBO stands for (polybenzoxazole). PBO is the next generation super fibre, offering the highest strength and modulus of any synthetic fibre on the market.
In fact PBO's strength and modulus are almost double that of Kevlar® (p-Aramid fibre). PBO is well known for 8 years as a fibre rigging core material and has proven its longevity.
