Celazole® PBI Plate, Rod and Tube
Celazole® PBI is the highest performance engineering thermoplastic available today. It offers the highest heat resistance and mechanical property retention over 400°F 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, Celazole® 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. Celazole® PBI has excellent ultrasonic transparency which makes it an ideal choice for parts such as probe tip lenses in ultrasonic measuring equipment.
Celazole® PBI is also an excellent thermal insulator. Other plastics in melt do not stick to PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.
A partial list of proven applications:
High Heat Insulator Bushings
Bushings used in hot runner plastic injection molds made of Celazole® PBI allow the plastic being molded to remain in melt as the part “freezes” in the cool mold. Bushings last longer and ease clean up since hot molten plastics do not stick to PBI. (Prior materials: Vespel* PI, Ceramic)
For an extra margin of safety, an aircraft engine manufacturer replaced connectors exposed to temperatures over 400°F (205°C) with Celazole® PBI. (Prior material: Vespel* PI)
Ball Valve Seats
Seats manufactured from Celazole® PBI excel in high-temperature fluid handling service. (Prior material: Metal)
