WebAbstract. Linear amorphous polymers are glasslike at low temperatures and become leathery at temperatures slightly higher than the glass transition temperature (T g ). These leathery polymers become rubbery at slightly higher temperatures, and crystalline polymers melt at the melting point ( T m ). WebThe melt flow index (MFI) or melt flow rate (MFR) is a measure for the ease of flow of melted plastics. It is often used in the plastic industry for quality control of thermoplastics. The method is described in the standards ASTM D1238 and ISO 1133. A small sample of about 5 grams is heated above its melting or softening point and forced to ...
