Polyurethane: resin, foam & rubber for casting, coating, laminating, moulding, forming, filling & supporting
Polyurethane is a versatile material: large and stable objects can be moulded very quickly from casting resin. PU foam is available in soft and hard, it is very light and is therefore well suited for fillings and for building light substructures, e.g. for heavy plaster moulds. Of course, PU foam can also be used for direct moulding. (Flexible) casting moulds can be made from polyurethane rubber, which are particularly suitable for casting plaster and concrete, for example. As high temperatures can occur when the PUR rubber hardens, the material is also particularly suitable for moulding plaster, concrete and other temperature-insensitive master models.
