Tungsten and Titanium dioxide filled VMQ polymer composites-a new lead free & flexible gamma ray-shielding materials.

Flexible & lead-free gamma-ray-shielding composites were prepared using Vinyl Methyl Silicone (VMQ) matrix with Tungsten (W) and Titanium dioxide (TiO2) as fillers. The VMQ composites filled with 30 Phr (parts per hundred rubber) TiO2 and 0-70 Phr W were prepared by two-roll mill method. The dispersion of the filler particles in the composite matrix was analysed using Scanning Electron Microscope.
