Abstract

Nella produzione di poliuretani elastomerici, in particolare in forma di suole da scarpa, mediante una miscela di reazione di poliuretano, è possibile evitare premiscele non conservabili, o conservabili solo limitatamente, costituite da poliolo e reticolante e ottenere, senza perdite, modifiche del reticolante che diventano immediatamente efficaci se si alimentano isocianato, poliolo e reticolante separatamente alla camera di miscelazione.In the production of elastomeric polyurethanes, in particular in the form of shoe soles, by means of a polyurethane reaction mixture, it is possible to avoid premixes that cannot be conserved, or can only be conserved to a limited extent, consisting of polyol and crosslinker and obtain, without losses, modifications of the crosslinker that they become immediately effective if isocyanate, polyol and crosslinker are fed separately to the mixing chamber.
