About PBI (Polybenzimidazole)

PBI (polybenzimidazole) such as Duratron® from Mitsubishi Chemical Advanced Materials, features the highest mechanical properties of any plastic above 400°F as well as the lowest coefficient of thermal expansion and highest compressive strength of all unfilled plastics. When compared to other reinforced or unreinforced engineering plastics, PBI features better wear resistance and load carrying capabilities at extreme temperatures.

Because of its extreme hardness, PBI can be difficult to fabricate and tends to be notch-sensitive.

Applications & Industries

Manufacturing

There are many benefits to using performance plastics in manufacturing environments. Replacing metal parts with longer-lasting plastic parts can decrease those costs, while increasing mean time between repairs (MTBR) and producing less waste.

Aerospace

There are a variety of reasons for using plastics – like PAI, ECTFE, PTFE, PEEK, PPSU, PVC-Acrylic, and much more – in aerospace applications, particularly airplanes.

Semiconductor

A wide variety of engineered plastics are used in the manufacturing of semiconductors, which are also known as microchips. Semiconductor manufacturing requires extreme precision and stability to prevent costly part failure.
