However, it is useful for the interpretation of polymer behaviour in extensional flow.<\/p>\n<p>The method is suitable for thermoplastics moulding and extrusion materials that can be extruded using a capillary extrusion rheometer, or an extruder with capillary rod die or other extrusion devices and have sufficient melt strength to be handled without difficulty.<\/p>\n<p>The method is applicable to chemically stable materials that produce a uniform extrudate free from heterogeneities, bubbles, unmelted impurities, etc.<\/p>\n<p>This method can provide information on<\/p>\n<p>\u2014     processability for all extrusion techniques,<\/p>\n<p>\u2014     the effect of mechanical and thermal history, and<\/p>\n<p>\u2014     the effect of chemical structure, such as branching, entanglements and molecular mass.<\/p>\n<p>This technique is one of a number of techniques that can be used to measure the extensional flow behaviour of a material.
