PBI is the highest performing engineering thermoplastic currently available.

This thermoplastic has the greatest heat resistance and best possible consistency of mechanical properties at temperatures above 205°C (400°F) of all unfilled plastics. Polybenzimidazole consists entirely of aromatic monomer units and has a very high melting point. PBI is strong, hard, resistant to pressure and exhibits good resistance under conditions of high chemical stress.

Of all thermoplastics, Duratron® CU60 PBI* offers the highest temperature resistance.

Compared to all other reinforced or unreinforced engineering plastics, Duratron® CU60 PBI* has better wear resistance and higher load carrying capacity at extreme temperatures. As an unreinforced material, Duratron® CU60 PBI* is very “pure” with respect to ionic impurities and does not emit gas. These properties make the material particularly attractive to semiconductor manufacturers, especially for vacuum chamber applications and the aerospace industry. The material has excellent ultrasonic transparency, making it ideal, for example, for probe tip lenses in ultrasonic measuring equipment.

Duratron® CU60 PBI* is also an excellent thermal insulator. Other molten plastics do not stick to Duratron® CU60 PBI*. These characteristics make this material ideal for contact seals and insulator bushings in plastic production and injection molding equipment. Typically, the material is used for major components to reduce maintenance costs and gain valuable production time. The material replaces metals and ceramic materials in pump parts, valve seats (high-tech valves), bearings, rollers and high-temperature insulators.
