Beschreibung
Zusammenfassung:	The invention concerns the field of chemistry and a reaction moulding method by injecting several constituents, the resulting compounds capable of being used, for example, in water piping systems, in the form of injected seals. The invention aims at obtaining, by injection moulding of several constituents at the interface of two or several materials, or in said interface region, improved adherence. Such aim is achieved by using a reaction moulding process which consists in injecting several constituents, whereby two substances are input, via injecting nozzles, into a tool, one of these substances being a polyamide and/or a polyester and/or a polycarbonate and/or a second polyurethane and/or a hardenable reaction substance, the other substance being a thermoplastic polyurethane and/or a thermoplastic polyurethane elastomer, and at least one of said two substances being used in modified state.
