PBO (Polybenzobisoxazole) fibers are notable for their exceptional strength, high modulus, and excellent heat resistance. These properties allow them to endure significant stress without breaking and remain stable at high temperatures. They are also highly flame-resistant, making them ideal for applications requiring fire resistance.
In the aluminum extrusion industry, PBO felt rollers are widely used because they can withstand temperatures up to 600 ℃ (1200 ℉). These rollers play a crucial role in transporting freshly extruded aluminum profiles along the production line, ensuring they cool down without sustaining scratches or damage. The initial rollers, which face the highest temperatures, particularly benefit from the use of PBO.
Beyond aluminum extrusion, PBO fibers have a wide range of applications in various industries. They are used in products like glassware, filtration systems, conveyor belts, sewing threads, and protective gear for welding or foundry work.
