Il melt flow rate MFR o melt flow index MFI (in traduzione italiana indice di fluidit) viene determinato mediante una misura di viscosit allo stato fuso e rappresenta la quantit di polimero espressa in grammi estrusa da un capillare di dimensioni standard sotto un peso standard in condizioni di temperatura e di tempo 10' secondo la norma ISO 1133 o ASTM D 1238
MFR = MFI = m x 600 / t Dnde: t = el intervalo de corte expresado en segundos (s) m = la masa de polmero extruido Mtodo B El Mtodo B tambin conocido como Procedimiento B es una medicin de velocidad de flujo de fusin temporizada automticamente utilizada para materiales que tienen velocidades de flujo que caen dentro del rango de 0 50 a 1 200 g / 10 minutos Para garantizar
