ABSTRACT:
Highly filled materials are disclosed. The material is formed from a composition of at least 4% by weight of a defined polar thermoplastic polymer, a plasticizer for the polymer and at least 90% by weight of an inorganic composition, including in elemental form. The compositions have a flexural modulus of less than 100 MPa. Preferably, the material provides attenuation against energy of greater than 0.1 keV that is equivalent to at least 0.1 mm of lead. The material may be used for containers, in apparel and other end-uses for protection against e.g. x-rays and gamma rays.
