Zylon (IUPAC name: 'poly(p-phenylene-2,6-benzobisoxazole)') is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. In generic usage, the fiber is referred to as PBO.

Zylon (IUPAC name: 'poly(p-phenylene-2,6-benzobisoxazole)') is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. In generic usage, the fiber is referred to as PBO.

Zylon has of tensile strength, which is 1.6 times that of Kevlar. Additionally, Zylon has a high Young's modulus of , meaning that it is stiffer than steel. Like Kevlar, Zylon is used in a number of applications that require very high strength with excellent thermal stability. The material has been used in body armour, in tennis racquets, table tennis paddles, and in snowboards, in various medical applications, and in some of the Martian rovers.
