CELAZOLE®
Best
Mechanical Properties to 800°F (425°C)
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.
Advantages
of Celazole
- Highest
mechanical properties of any plastic over 400°F (205°C)
- Highest
heat deflection temperature of any plastic at 800°F (425°C), with a
continuous service capability of 750°F (400°C) in inert environments,
or 650°F (345°C) in air with short term exposure potential to 1,000°F
(540°C)
- Lowest
coefficient of thermal expansion and highest compressive strength of
all unfilled plastics
Celazole
PBI is the highest performance engineering plastic available today. It
offers the highest heat resistance and mechanical property retention over
400°F (205°C) of any unfilled. It has better wear resistance and load
carrying capabilities at extreme temperatures than any other reinforced
or unreinforced engineering plastic.

Celazole*
PBI is the highest performance engineering plastic available from Quadrant
EPP. It offers the highest mechanical properties of any thermoplastic
above 400° F (205° C). Celazole is ideal for high heat bushings,
connectors and valve seats. Celazole is extremely hard and can offer a
challenge to fabricate. Fabrication instructions can be furnished by Quadrant
EPP.
