Polyurethane: resin, foam & rubber for casting, coating, laminating, moulding, shaping, filling & supporting.
Polyurethane is a versatile material: large and stable objects can be cast very quickly from casting resin. Polyurethane foam comes in soft and hard, it is very light and therefore well suited for fillings and to build light substructure moulds e.g. for heavy plaster moulds. Of course, you can also mould directly with the PU foam. From polyurethane rubber (flexible) casting moulds can be made, which are particularly well suited for casting e.g. gypsum and concrete. Since high temperatures can arise during the curing of the PUR rubber, the material is also particularly suitable for moulding plaster, concrete and other temperature-insensitive master models.> read more
