PBI Plate, PBI Rod, Celazole Plate, Celazole Rod, Duratron Plate, Duratron Rod
Duratron CU60 PBI is the highest performance engineering thermoplastic currently available. It has the highest heat resistance and mechanical properties of all unfilled plastics at temperatures above 205°C. It has better abrasion resistance and load-carrying capacity at extreme temperatures than any other reinforced or unreinforced engineering plastic.
As an unreinforced material, Duratron CU60 PBI is very "pure" with respect to ionic impurities and does not outgas (with the exception of water). These very attractive properties allow the material to be designed for use in vacuum chambers for semiconductor devices, as well as in the aerospace industry. Duratron CU60 PBI has excellent ultrasonic transparency, which makes it ideal for components such as probe tip lenses in ultrasonic measurement equipment.
Duratron CU60 PBI is also an excellent thermal insulator. Other molten plastics will not bond to the Duratron CU60 PBI. These properties make it ideal for contact sealing and insulating bushings in plastic production and molding equipment. Often Duratron CU60 PBI can be used in critical components to reduce maintenance costs and increase valuable production "uptime". It replaces metals and ceramics for pump components, valve seats (high-tech valves), bearings, rollers and high temperature insulators.

Applications;
High temperature insulating bushing
Bushings machined from Duratron CU60 PBI for hot runner systems for plastic injection molding allow the plastic to be molded to remain molten even if the part is "frozen" in a cooling mold. And the hot molten plastic won't stick to the Duratron CU60 PBI, making the bushing last longer and making it easier to clean. (Previous Materials: Vespel® PI, Ceramic)
electrical connector
For a higher safety factor, an aircraft engine manufacturer replaced connectors exposed to temperatures in excess of 205 °C (400 °F) with Duratron CU60 PBI material. (Prior material: Vespel® PI)
Ball Seat
Seats machined from Duratron CU60 PBI for high temperature fluid control with outstanding performance. (previous material: metal)
Clamp Rings
Duratron CU60 PBI is machined for gas plasma etch equipment and has a longer life compared to polyimide (PI) parts due to reduced high energy erosion rates. Because they don't need to be replaced as often, they gain valuable production "uptime." (Prior material: Vespel® PI)
