Premadex® is manufactured as a liquid at 95° to 100°C and can be poured at the factory directly into suitable prepared assemblies, such as glove box panels, neutron source containers and shielding doors. Alternatively, particularly large assemblies can be filled on site by arrangement.
It is also available in block form. Standard blocks are 400mm x 300mm or 280mm x 280mm, either 50mm or 75mm thick. They are easy to trim or cut to shape. Blocks can be produced in non-standard sizes to suit individual requirements.
