Polybenzimidazole Thermoplastic Polymer
Polybenzimidazole, better and more easily known as PBI, is perhaps the most high-performance engineered thermoplastic material available. PBI exhibits the highest heat resistance of any thermoplastic, retaining its mechanical properties at temperatures above 400°F (204°C). At extreme temperatures, it offers the best wear resistance and load-bearing capacity than any other thermoplastic.
These properties, along with its extremely high hardness, make PBI a popular material for parts and components used in military, law enforcement, and firefighting applications.
Injection Molding with Polybenzimidazole
Though polybenzimidazole thermoplastic is notoriously difficult to machine and fabricate, Stack Plastics has the experience and the expertise to deliver injection molded PBI parts with superior accuracy and repeatability. We can achieve the tight tolerances your parts require.
In addition to PBI injection molding, we offer numerous secondary services, including assembly, pad printing, sonic welding, and more. This enables us to provide parts that are more complete, with less additional processing required.
