Scope

This document describes a method for determining the tensile and fracture properties of thermoplastic materials in their molten state by measuring the melt force generated during the deformation of a melt beam under specific extrusion temperatures and traction conditions.
This document is applicable to thermoplastic molding and extrusion materials that are extruded using a capillary rheometer or an extruder equipped with a die, and have sufficient melt strength.
This document is also suitable for thermoplastic materials with stable chemical properties, which can form extrudates free from heterogeneities, bubbles, and un-melted impurities.
