Our bags are manufactured from a combination of aluminium and a coating of high grade Polymide plastic

Polyimide is clinically proven to show a good resistance to X-ray radiation.

Polyimide Resistance: Polyimide is often reported as having one of the highest radiation resistance levels among all polymers.

Polyimide has been shown to retain its properties at extremely high doses, with reported resistance levels up to 100 MGy (100,000 kGy).

It maintains good insulation performance even after significant irradiation, although some properties like insulation resistance may decrease with increasing fluence.

When exposed to X-ray Free-Electron Lasers (XFEL), polyimide-based devices did not experience structural destruction, unlike other polymers like PDMS.

When choosing the best plastic polymer to coat our aluminium material we considered PEEK and Polyimide – the 2 best plastics for radiation resistance.

In conclusion, while both materials perform well in radiation environments, lab results consistently indicate that polyimide has a higher tolerance to extreme radiation doses, including X-rays, compared to PEEK.

Polyimide (PI) material shows good to excellent resistance to X-ray and other forms of ionizing radiation, significantly outperforming many other polymers.

Polyimides  also demonstrate excellent radiation tolerance and are commonly used in spacecraft and high-energy physics research facilities like CERN. They are reported to have an even higher radiation resistance than PEEK, with stability up to 100 MGy in some tests. The high thermal stability and robust chemical structure contribute to their durability under radiation exposure.

Polyimide (PI) is as industry wide know to be the superior plastic for absorption of x  rays and gamma rays. See graph testing radiation resistance of Polyimide (PI ) compared to other radiation aborbing materials.

Note : PI is the industry code for Polyimide.
