Abstract

An elastomeric matrix impregnated with at least 70% by weight of a high atomic number radiopaque substance, and cured with an organic peroxide, to form carbon-carbon links between elastomer molecular chains. The radiopaque elastomeric matrix may be used to create a flexible, lightweight, carbon-carbon linked, multilaminated protection material against ionizing radiation. The multilaminated protec tion material may include a mechanical reinforcement cloth layer to avoid material expansion or rupture; and additional external elastomeric layers for protection against aging, physical, biological and chemical hazards, as well as allowing mechanical memory of the material and easy cleaning, desinfection and sterilization. These layers are directly merged or incorporated into a single, fused sheet with the radiopaque elastomeric matrix, without the use of glues or adhesives, during a cure and pressure application wherein the elastomer molecules create reticulated carbon-carbon links between the internal and external elastomeric layers and through the pores of the reinforcement layer. The multilaminated material allows production of colored, flexible, lightweight, durable radiation protection articles for medical, dental, and industrial uses.
