ORE-FILLED COMPOSITIONS

摘要

Highly filled materials are disclosed. The material is formed from a composition of 4-19 % by weight of a defined polar thermoplastic polymer, 0-10 % by weight of a plasticizer and 81-96 % by weight of an ore concentrate. 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, as sound proofing and in electrical applications, depending on the particular ore selected.
