PBO yarn, the full name is "poly-para-phenylene benzobis-oxazole yarn", is an existing aromatic heterocyclic polymer.
It is a compound with very excellent properties in materials and is also a comprehensive compound in the field of high-performance yarns at home and abroad.
One of the high-performance yarns with excellent performance. Its modulus is twice that of para-aramid yarn and its strength exceeds steel.
Yarn and carbon yarn have excellent impact resistance, friction resistance and dimensional stability, as well as good flame retardancy.
It is regarded as a new generation of yarn for advanced structural composite materials in aviation, aerospace and other fields after aramid yarn.
PBO yarn widely used in military and civilian fields, as below: Helicopter and rocket casings in aerospace and aviation. Bulletproof helmets in the field of military protection technology. Also used as fire protective clothing in civil fields.
