Epoxy granite VS cement-based concrete

Polymer concrete or epoxy granite as alternatives to cast iron, made fromMade from densely packed rocks of various sizes, filler and a low proportion of epoxy resin binder.Polymer concrete has extraordinary temperature stability and has approximately 10 times higher damping properties than cast iron.

Developed by Swiss machine builders in the 1980s, composite bases have had limited use in standard machinery, but are increasingly used in specialty machine tools and other special machinery applications that require high precision.In high-speed processing, polymer concrete has become the latest technology for all non-moving parts of the machine structure, such as beds, beams and columns.

While the original recipe for the polymer composite came from the concrete filling of the base of the machine tool and includedconcrete, but recent formulations mainly consist ofEpoxy resinin composite materialsquartz或graniteMaterial composition.Therefore, the name was changed from polymer concrete to epoxy granite.

cement based concreteDue to its hygroscopicity, the internal structure will change over time and it does not have dimensional stability. Therefore, it cannot be used for the main structure of precision machine tools and can only provide a reasonably stable foundation for non-self-supporting very large machines.
