Resumen<\/b><\/strong><\/h2>\n

M\u00e1quina de ensayo del \u00edndice de fluidez: equipo especializado para medir el \u00edndice de fluidez de los termopl\u00e1sticos en determinadas condiciones, que permite determinar indirectamente el peso molecular de los pol\u00edmeros de alto peso molecular. El \u00edndice de fluidez (MFR o MI) de un termopl\u00e1stico se refiere a la masa o el volumen de pl\u00e1stico fundido que pasa a trav\u00e9s de la salida de una probeta est\u00e1ndar cada 10 minutos a una temperatura y carga determinadas, expresado como valor MFR (MI) o MVR, lo que permite distinguir las caracter\u00edsticas de flujo viscoso del termopl\u00e1stico en estado fundido. Es adecuado para ensayar pl\u00e1sticos de ingenier\u00eda como el policarbonato, la poliarilsulfona, los fluoropl\u00e1sticos, el nailon, etc., con altas temperaturas de fusi\u00f3n, as\u00ed como para ensayar pl\u00e1sticos como el polietileno (PE), poliestireno (PS), polipropileno (PP), resina ABS, polioximetileno (POM), resina de policarbonato (PC), etc., con bajas temperaturas de fusi\u00f3n. Reviste gran importancia para garantizar la calidad de las materias primas y los productos de pl\u00e1sticos termopl\u00e1sticos y fibras qu\u00edmicas.<\/p>\n

\u00c1mbito de aplicaci\u00f3n<\/b><\/strong><\/h2>\n

Se utiliza ampliamente en f\u00e1bricas, centros de control de calidad de productos, instituciones de investigaci\u00f3n y otras entidades en los \u00e1mbitos de la producci\u00f3n, la inspecci\u00f3n, el desarrollo, la investigaci\u00f3n y otros campos relacionados con los pl\u00e1sticos.<\/p>\n
