Regarding ionic impurities, polybenzimidazole is a very pure unreinforced polymer that just emits water. Due to its properties, polybenzimidazole is particularly appealing to semiconductor manufacturers for vacuum chamber applications.
Since poly benzimidazole is transparent to ultrasonic waves well, it is a great material for probe-tip lenses and other components of ultrasonic measurement equipment.
Another effective thermal insulator is polybenzimidazole. Other polymers in the melt do not stick to polybenzimidazole. Due to these characteristics, polybenzimidazole is appropriate for contact seals and insulator bushings in plastic manufacturing and moulding machinery.
The Global Polybenzimidazole resin market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Polybenzimidazole (PBI) film coating for improved hypervelocity impact energy absorption for space applications.The hypervelocity impact ballistic performance of the system could be enhanced by using polybenzimidazole (PBI) as a film coating over standard composite designs.
PBI coated composite samples were tested in a simulation laboratory for their ability to withstand the harsh conditions of Low Earth Orbit, including high vacuum, heat cycling, atomic oxygen, and ultraviolet radiation.
Following LEO exposure, it was shown that PBI coated composites experienced less mass loss and surface erosion than uncoated samples. The most ideal material for this application can be thought of as polymer matrix composite material due to its low density, high specific strength, and high specific stiffness.
However, factors including atomic oxygen (AO), high vacuum, temperature cycling, ultraviolet radiation (UV), and hits from micrometeoroid orbital debris (MMOD) have an impact on materials in space that are not present on Earth.
Because MMOD impacts occur in the Low Earth Orbit (LEO) at hypervelocity ranges of roughly 7–15 km/s, they pose a very serious risk to spacecraft.The PBI coated composites were subjected to hypervelocity impact tests at impact velocities of 2.5 to 3 km/s.
The results of the trials demonstrated that the PBI film coating considerably boosted the composite system’s capacity to absorb energy.
The efficiency of PBI coating as a hypervelocity shield was confirmed by the finding that the influence of thickness increase due to film application on energy absorption was also found to be minimal.
