New PET IV tester gathers data more easily

摘要

The Davenport PETPlus intrinsic viscosity(IV)measurement instrument is a compact device that lets users measure IV without solvents.Molten PET is extruded through a calibrated die by nitrogen gas under pressure and the LVDT probe movement against time is recorded and displayed.The system measures the optimum flow rate and calculates intrinsic viscosity.The device also measures the degradation factor and provides the mean and standard deviation for a batch.
