Product DescriptionThe Melt Flow Index is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer in grams flowing in 10 minutes through a capillary of specific diameter and length by pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures as specified in the ASTM D1238 and ISO 1133 Test StandardsThe Melt flow rate is an indirect measure of molecular weight, a high melt flow rate corresponding to a low molecular weight. At the same time, melt flow rate is a measure of the ability of the material's melt to flow under pressure. Melt Flow rate is inversely proportional to the viscosity of the melt at the conditions of the test, though it should be borne in mind that the viscosity for any such material depends on the applied force. Ratios between two melt flow rate values for one material at different gravimetric weights are often used as a measure for the broadness of the molecular weight distribution.Melt flow rate is commonly used for polyolefin * ¹«´Ü¼öÁý¹× º¹À縦 ±ÝÇÕ´Ï´Ù . »óÇ°Á¤º¸°í½Ã Á¦Ç°¸í ¸áÆ® ¿ëÀ¶Áö¼ö (MI-MFI) ÃøÁ¤±â ÆǸŰ¡°Ý °¡°Ý¹®ÀÇ ºê·£µå RAY-RAN Á¦Á¶»ç UK
