DURATRON® CU60 PBI
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 PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.Applications:
- High Heat Insulator Bushings
- Electrical Connectors
- Ball Valve Seats
- Clamp Rings
Note: DURATRON® CU60 PBI is extremely hard and can be challenging to fabricate. Polycrystalline diamond tools are recommended when fabricating production quantities. DURATRON® CU60 PBI tends to be notch sensitive. All corners should be radiused (0.040” min.) and edges chamfered to maximize part toughness. High tolerance fabricated components should be stored in sealed containers (usually polybags with desiccant) to avoid dimensional changes due to moisture absorption. Components rapidly exposed to temperatures above 400°F (205°C) should be “dried” prior to use or kept dry to avoid deformation from thermal shock.
- Highest mechanical properties of any plastic above
- Highest heat deflection temperature 800°F (427°C), with a continuous service capability of 750°F (399°C) in inert environments, or 650°F (343°C) in air with short term exposure potential to 1,000°F (538°C)
- Lowest coefficient of thermal expansion and highest
compressive strength of all unfilled plastics
