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, radar transparent performance, 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.
