Demron is a radiation-shielding fabric. 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. It has a significant electron cloud that either deflects or absorbs incoming 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.
