Procedure for microencapsulation of phase change materials by spray-drying

A process for producing microcapsules containing phase-change materials (PCMs) by means of the physical technique of "spray_drying". PCMs will be microencapsulated by using solutions thereof and of polymers, more specifically polyethylene, and ethyl vinyl acetate (EVA) as copolymer, as enc...

Beschreibung
Zusammenfassung:	A process for producing microcapsules containing phase-change materials (PCMs) by means of the physical technique of "spray_drying". PCMs will be microencapsulated by using solutions thereof and of polymers, more specifically polyethylene, and ethyl vinyl acetate (EVA) as copolymer, as encapsulating agents, in an appropriate and non-aqueous solvent. Procedimiento para producir microcápsulas conteniendo materiales de cambio de fase (PCMs) mediante la técnica física de ¿secado por pulverización¿. Los PCMs serán microencapsulados utilizando disoluciones de éstos y de polímeros, más concretamente polietileno y etilvinilacetato (EVA) como copolímero, como agentes encapsulantes, en un disolvente adecuado y no acuoso.
