Polybenzimidazole (PBI) is the most technically advanced thermoplastic that we have in our range. It offers the highest heat resistance and mechanical retention above 205°C (400°F) of unfilled plastics. It has better wear resistance and load capacity at extreme temperatures than any other reinforced or unreinforced construction plastic.
We market PBI under the trade name Duratron® CU60 and is the highest performance engineering thermoplastic available today.
As an unreinforced material, Duratron CU60 PBI is very “clean” in terms of ionic contamination and does not outgas (except water). These properties make this material very attractive to vacuum chamber semiconductor manufacturers. Duratron CU60 PBI has excellent ultrasonic transparency making it an ideal choice for parts such as probe tip lenses in ultrasonic measurement equipment.
Duratron CU60 PBI is also an excellent thermal insulator. Other molten plastics do not stick to Duratron CU60 PBI. These properties make it ideal for contact seals and insulator bushings in plastic production and molding equipment.
