Melt Flow Indexers

The Davenport Melt Flow Indexer is used to determine the melt flow properties of a polymer by extruding it in a molten state, through a calibrated die using a reference weight. It is used extensively in production and quality control to ensure batch-to-batch consistency and is renowned for accuracy, repeatability, and reproducibility of results. Two models are available, the manual MFI-9 and the automatic MFI-10.

PETPlus Instrument for the Intrinsic Viscosity (IV) Measurement of PET Polymers

The Davenport PETPlus is a unique test instrument designed for fast and safe solvent-free intrinsic viscosity (IV) measurement of moisture-sensitive polyethylene terephthalate (PET). The instrument can be operated in stand alone mode to provide on screen results or used with our powerful data analysis software package NEXYGENPlus PET. Existing solvent methods for determining IV involve the need to handle and dispose of toxic solvents. This preferred method is both kinder to the environment and saves on the high costs of purchase and disposal of solvents.

Friction Testers

Used throughout the packaging and printing industries, the LFPlus universal test machine can be used to accurately measure the static and kinetic friction of a variety of materials. The NEXYGEN MT software package will accurately record the peak and transient friction forces, as well as the static and kinetic co-efficient of friction values. These values are of importance in a wide range of industries including blown film, plastic sheet, paper and coating manufacture.
