Duratron CU60 PBI

Celazole
Compression Molded Grade • Black Color

 

Description

Duratron CU60 PBI is the highest performance engineering thermoplastic available today. It offers the highest heat resistance and mechanical property retention over 400 degreesF 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.

Features
  • Highest mechanical properties of any plastic above 400 degreesF
  • Highest heat deflection temperature 800 degreesF, with a continuous service capability of 750 degreesF in inert environments, or 650 degreesF in air with short term exposure potential to 1,000 degreesF
  • Lowest coefficient of thermal expansion and highest compressive strength of all unfilled plastics
