Applications in Polymer Synthesis and Processing

Measure key Chemical and Physical Properties

Online Polymer analysis.  The IsoChem provides determination of  key properties across all stages of polymer, monomer, and precursor production. Applications include polymer and monomer production, processing, finished product quality and even recycling. 

The list below is only a sampling of the IsoChem measurement solutions in the Polymer industry. The many applications of Near Infrared analysis of polymers have helped manufactures large and small save time and money. Contact us to learn how we can help with your analysis needs.

Key Measurement Advantages

  • Powerful, Flexible Analysis- The IsoChem Analyzer comes in several different configurations for laboratory and process measurements of a variety of products. Rugged options such as our Hot Melt Probes allow for direct measurements at the extruder or in the melt flow.
  • Any State - Measure properties of a variety of liquids and solids including melts, pellets, film, sheets and other extruded plastics. Melt properties are easily measured directly in solids for a quick QC check. And process-ready probes stand up to extruder and hot melt temperatures and pressures.
  • Online Measurement- Take key measurements online to improve process control. Take measurements directly at reactors, extruders, and other process units. See our Process Pages for more information about our complete process measurement solution.
  • Multi-point Management - The Multiplexer allows for measuring up to 20 process points with one analyzer.  Integrate real time monitoring of various streams for improved process control.
  • Process Ready - IsoChem Online Analyzers are suitable for all process environments and can incorporate inline probes, sample cells, or sample conditioning systems as needed.  Product properties are analyzed and fed directly into the DCS or process control unit for real time feedback and control of final product.
