Duratron® PBI


Product Details

Duratron® CU60 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, Duratron CU60 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 CU60 PBI has excellent ultrasonic transparency which makes it an ideal choice for parts such as probe tip lenses in ultrasonic measuring equipment.

Duratron CU60 PBI is also an excellent thermal insulator. Other plastics in melt do not stick to Duratron CU60 PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.

Duratron® CU60 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 (see Figures 26 & 27).

  • High Heat Insulator Bushings

    Bushings used in hot runner plastic injection molds made of Duratron CU60 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 Duratron CU60 PBI. (Prior materials: Vespel® PI, Ceramic)

     

  • Electrical Connectors

    For an extra margin of safety, an aircraft engine manufacturer replaced connectors exposed to temperatures over 400°F (205°C) with Duratron CU60 PBI. (Prior material: Vespel® PI)

     

  • Ball Valve Seats

    Seats manufactured from Duratron CU60 PBI excel in high temperature fluid handling service. (Prior material: Metal)

     

  • Clamp Rings

    Parts machined from Duratron CU60 PBI for gas plasma etching equipment last longer than polyimide parts due to reduced high energy erosion rates. Because they need replacement less often, valuable production "uptime" is gained. (Prior material: Vespel® PI)
