(From Copilot) Polybenzimidazole (PBI) is a high-performance polymer with exceptional thermal, chemical, and mechanical stability. Its unique properties make it suitable for various industrial applications, including:

Protective Clothing: Used in firefighter gear, astronaut suits, and welders’ apparel due to its non-flammability and high-temperature resistance.
Aerospace and Automotive: Ideal for components in aircraft engines and automotive insulation pads, gaskets, and seals.
Chemical Processing: Resistant to corrosive substances, making it valuable in industries dealing with acids, bases, and solvents.
Semiconductor Manufacturing: Utilized in vacuum chamber applications due to its cleanliness and resistance to outgassing.
Ultrasonic Equipment: Suitable for probe-tip lenses in ultrasonic measurement devices.

Research has continued to develop other forms of PBI. Here we make this engineering plastic solution processible, so you can explore its applications by coating and printing.
