A shapeable composition comprising a homogeneous mixture of (a) at least one particulate ferrite material having magnetic properties, (b) at least one water-soluble or water-dispersible organic polymeric material, and (c) water, in the composition the components (a), (b) and (c) being present in a proportion by volume of the composition of respectively, 40 to 90%, 2 to 25%, and not more than 60%, a product produced therefrom, and a process for producing said product by removing water from the composition. The composition optionally contains an additive capable of insolubilising the organic polymeric material with respect to water. |
