Demron

For the same weight it has slightly lower radiation protection than lead shielding, but is flexible.

[1] The composition of Demron is proprietary information, but it has been described as a non-toxic polyethylene and non-PVC-based polymer fused between two layers of a woven fabric.

The polymer molecule imitates the electronic traits of heavy metals, commonly employed for shielding against radiation.

[2][3] It is roughly three to four times more expensive than a conventional lead apron, but can be treated like a normal fabric for cleaning, storage and disposal.

[4] More recent uses for Demron include certified first responder hazmat suits as well as tactical vests.
