Duratrone® PBI - polybenzimidazol
Duratron® PBI is the highest performance engineering thermoplastic available today. It offers the highest heat resistance and mechanical property retention of any unfilled plastic It has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or unreinforced engineering plastic.
As an unreinforced material, Duratron PBI is very "clean" in terms of ionic impurity and it does not outgas (except water). These characteristics make this material very attractive to semiconductor manufacturers for vacuum chamber applications. Duratron PBI has excellent ultrasonic transparency which makes it an ideal choice for parts such as probe tip lenses in ultrasonic measuring equipment.
Duratron PBI is also an excellent thermal insulator. Other plastics in melt do not stick to Duratron PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.
- Bushings used in hot runner plastic injection molds
- connectors exposed to temperatures over 205°C
- Seats manufactured from PBI excel in high temperature fluid handling service
- arts machined from PBI for gas plasma etching equipment last longer than polyimide parts due to reduced high energy erosion rates
- Highest mechanical properties of any plastic above 204°C
- Highest heat deflection temperature 427°C, with a continuous service capability of 399°C in inert environments, or 343°C in air with short term exposure potential to 538°C
- Lowest coefficient of thermal expansion and highest compressive strength of all unfilled plastics
Engineering plastics and their products can be ordered from TechPlasty. Materials in the same group from different manufacturers are not always directly interchangeable because they may not all have the same technical parameters. Our technical consultants, who have many years of experience in the field of engineering plastics, will be pleased to advise you on the differences in the individual materials, especially in the boundary conditions. Detailed technical data of individual manufacturers' materials can be found in their data sheets.
