Processing/ Proceso de moldeo Pleasepreheat materials at 60~70ºCfor6~10hoursbefore processing. Then mix fully the wholedrumofPOLandotheradditivesaccording tothe following table. Finally, respectively transfer POLand ISO to their corresponding tanks. Antes del moldeo, todos los componentes deben estar en estado líquido. Las materias primas deben precalentarse a bajas temperaturas en un tanque de calefacción de 60-70 °C (generalmente 6-10 horas, dependiendo de la cantidad y el tamaño del volumen de envasado. Es que el tiempo de fusión es diferente) antes de su uso. Los aditivos agregados deben mezclarse completamente con el material poliol antes de su uso y luego colocarse en el tanque de material. La cantidad de aditivos añadidos se muestra en la siguiente tabla.
