Modulus : 1150cN/dtex (AS) - 1720cN/tex (HM)
Degradation temperature : 650°C
Density : 1.54g/cm3 (AS)-1.56g/cm3 (HM)
Color: yellow-orange


Applications of PBO

PBO has the highest performances to high temperatures and high mechanical stress, but it’s expensive. So PBO is generally used in advanced and demanding environments.
Industry: glassware, filtration, conveyor belts, sewing thread, welding or foundry protection, joints, etc.
