  • Flexible polymer sheet filled with heavy metal having a low total weight
    Patent number: 7488963
    Abstract: A thin, light-weight, flexible sheet product useful for the manufacture of radiation attenuation garments. The sheet product is a polymeric material and includes a heavy loading of high molecular weight metal particles. The sheet product is formed from a polymer latex dispersion into which a high molecular weight metal particles are dispersed, where the latex retains a sufficiently low viscosity to be pourable and allow casting of the sheet product.
    Type: Grant
    Filed: March 19, 2007
    Date of Patent: February 10, 2009
    Assignee: Bar-Ray Products, Inc.
    Inventors: Arthur P. Lagace, Ronald E Blocher
