High Modulus PBO Long Filaments

PBO filament is an aromatic heterocyclic fiber composed of rigid functional units and has a very high orientation along the fiber axis. The structure gives it ultra-high modulus, ultra-high strength, and excellent temperature resistance, flame retardant, chemical stability, impact resistance, insulation and other application properties. It is a new generation of super fiber used in aerospace, national defense, rail transportation, electronic communications and other fields after aramid fiber.

Characteristics

PBO, for poly(p-phenylene-2,6-benzobisoxazole) is a special material in fibres with high mechanical and thermal performance.

Its mechanical properties are more than aramid fiber, with the advantages of ultra-high strength modulus, PBO fiber has excellent flame retardant and thermal resistance its （degradation temperature : 650°C, working temperature 350°C-400°C ), itultra-low dielectric loss, transmission and light spun ability.

application

PBO fiber has wide application prospects in aerospace, national defense, police and fire fighting equipment, rail transit, electronic communication and civil protection.
