IMPROVED SHELF LIFE OF POLYOL BLENDS CONTAINING HALOGENATED OLEFINS BY ENCAPSULATION OF ACTIVE COMPONENTS |
摘要 |
The shelf life of polyurethane polyol pre-blends containing halogenated olefins is extended by encapsulation of active components such as catalysts and/or surfactants. The active component is encapsulated in a crystallizable or thermoplastic polymer. The encapsulated particles have a size of 2,800 microns or less and the active components are not significantly leaked out, particularly in the presence of halogenated olefins. |
