About: Demron

Demron is a radiation-shielding fabric. Weight-for-weight the material has slightly lower radiation protection than lead shielding, but it is flexible. 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 mimics some of the electronic properties of the heavy metals usually used as radiation shielding, and has a large electron cloud so that incoming radiation will deflect or be absorbed by it. 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. More recent uses for Demron include certified first responder hazmat suits as well as tactical vests.
