Celazole PBI

Celazole PBI (black) offers the highest temperature resistance
and best mechanical property retention over 200°C of all unfilled
thermoplastics. Celazole PBI is very "clean" in terms of ionic impurity and
does not outgas (except water). These characteristics make this material
extremely attractive to high-tech industries such as semiconductor and
aerospace industries. Usually Celazole PBI is used in critical components
to decrease maintenance costs and to gain valuable production "uptime". It
is used to replace metals and ceramics in pump components, valve seats (high
tech valves) bearings, rollers, high temperature insulators.

Common Uses for Celazole PBI

Celazole PBI High Heat Insulator Bushings

Hot runner systems needed a material that could endure the high temperatures
but did not "stick" to the finished moulded parts.
Celazole PBI machined bushings outperformed all other materials tested in
the application. The benefits are that Celazole PBI is unique in its ease
of clean up in hot runner systems. Moulded parts do not stick to Celazole
during their "freeze" cycle in the mould.

Celazole PBI Vacuum Cups

Engineers were looking for a more cost-effective solution for an extremely
high temperature glass handling application. Celazole PBI outperformed
prior materials and reduced the component cost. Celazole PBI proved more
wear resistant than polyimides. The Celazole PBI cups reduced product
breakage compared to the ceramic tested. It also proved more cost effective
than pressed carbon or polyimide materials.
