PBO Short Staple Fiber 1.7D~3.3D / 38mm、51mm、76mm

PBO, for poly(p-phenylene-2,6-benzobisoxazole) is a special material in fibres with high mechanical and thermal performance. PBO fiber is light-weight,flame resistant,high temperature resistant, and owns excellent strength and good wave transmittance, etc., with its comprehensive performance being the best of organic fiber. It could be widely used in aerospace, military equipment, fire protection and other applications apart from aramid fiber.

application

As a typical dual-use material with promising prospect,PBO fiber could be widely used in aerospace,national defense,fire-fighting equipment,rail transit,electronic communication,civil protection and other applications：

PBO staple fiber spun yarns can used as fireproof cloth for fire rescue clothing.

Spun yarn made by PBO fiber with steel fiber can weaving thermal resistant tape.

Thermal resistant filter made by PBO staple fiber felt etc.

PBO fiber can absorb a large amount of impact energy when impacted, which is an excellent impact resistant material. The maximum impact load of PBO fiber composite can reach 3.5KN and the energy absorption is 20J. The wear resistance of PBO is good, and the wear cycle is five thousand times.

PBO fiber at a high temperature of more than 300°C can reflect the better wear resistance properties, and its strength retention rate is about 45% after 100 hours of treatment in the air at 300°C.

PBO fabric lightly and flexiblility improved comfortability and mobility and it is ideally heat and fire resistant workwear material.
