Polymer Char is a company which designs and manufactures instrumentation for polymer analysis.


Polymer Char was founded by B. Monrabal in 1992 in the Valencia Technology Park, in Spain, being registered with the name of Polymer Characterization, S.A.

Its initial goal was to develop a commercial Crystallization Analysis Fractionation (CRYSTAF) instrument based on technology developed by Monrabal at Dow Chemical Company laboratories in the Netherlands to measure chemical composition distribution in semicrystalline polymers.

A CRYSTAF prototype was presented at Pittcon in 1994. The first product was acquired in 1995 by a petrochemical company in South Korea.

The company has also developed techniques and instruments for polymer characterization, and more specifically, for polyolefin (polyethylene and polypropylene) characterization.

Polymer Char's technology is present in the petrochemical and research and development industries in over 20 countries in North America, South America, Europe, Africa, and Asia.[1]

Analytical instrumentation[edit]

The company develops analytical instruments for polymer analysis.

Chemical composition distribution

Chemical composition distribution (CCD) together with the molar mass distribution (MMD) and their interdependence define the microstructure of a polyolefin. CCD is often the most discriminating feature of a complex polyolefin. Some instruments in Polymer Char’s range are available for this purpose:

  • CRYSTAF: instrument intended for the fast measurement of the chemical composition distribution (CCD) in polyolefins (crystallization analysis fractionation).[2]
  • TREF: performs the temperature rising elution fractionation (TREF) technique for the characterization of CCD in polyolefins.[3]
  • Crystallization elution fractionation (CEF): high-throughput chemical composition distribution analyzer by CEF
  • TGIC: technique for the analysis of low crystallinity polyolefins implemented by a fully automated instrument.
Molar mass distribution
Intrinsic viscosity
  • IVA: automated instrument for intrinsic viscosity analysis of polymers with dissolution temperature up to 200 °C.
Bivariate distribution
Preparative fractionation
  • PREP mc2: preparative instrument to fractionate polymers by molar mass or composition (TREF or CRYSTAF).
  • PREP C20: a column-based preparative fractionation instrument, capable to fractionate up to 20 grams of polymer.
Soluble fraction
  • CRYSTEX QC: fully automated instrument for amorphous phase determination in PP/EP manufacturing QC laboratories.
  • CRYSTEX 42: high-throughput system for simultaneous measurement of the soluble fraction, ethylene content and intrinsic viscosity in a fully automated process for up to 42 samples.
Infrared detectors

Part of the techniques and instruments were developed with Petrochemical companies and Research Institutes from United States, Belgium, Finland, Germany and Japan. The company supplies in over 35 countries around the globe Analytical Services for Polymer characterization.[1]
