PBO stands for Polybenzobisoxazole, a synthetic polymer invented by SRI International and is currently manufactured by Toyobo Corporation in Japan. The trademark name for PBO is Zylon. Zylon is 1.6 times stronger than Kevlar and can also withstand higher temperatures.
PBO felt belts are widely used in the aluminum extrusion industry.
For aluminum extrusion,
PBO usually can withstand temperatures up to 1200℉/600℃.

After being extruded, the profile falls into rollers that convey it further down the line. The first rollers have to hold the most amount of heat, so we use PBO.
