Polymer tungsten sheet is an important material in radiation shielding as it has good shielding performance against X-rays and other radiation sources. More importantly, the radiation shielding performance of polymer tungsten is better than traditional lead materials. Therefore, it has been used to replace lead to fabricate different medical shields to protect medical staffs and patients.

In addition, as the tungsten polymer radiation protection sheet has strong plasticity and is easy to process, it can be flexibly cut into various shapes and is suitable for different uses. For radiation shielding, non-toxic polymer tungsten sheet is developed to replace toxic lead sheet.
According to the standard of GB/T 3672.1-2002, polymer tungsten sheet is divided into two types: molded sheet and calendered sheet. Generally, the dimensional tolerance of the molded sheet is supplied according to M2 level, and the dimensional tolerance of the calendered sheet is supplied according to ST2, SL2, SW2.
