Polymer Char is the leading instrumentation company fully devoted to the microstructure characterization of Polyolefins. Our research and development efforts are focused on the various separation methods to analyze Polyethylene and Polypropylene resins. The instruments commercialized cover the whole spectrum of Polyolefins’ characterization by separation techniques.
Polymer Char instruments are intended both to University Departments with research jobs related to Polyolefin Characterization and also to Petrochemical Companies with analytical services Laboratory, Research and Development groups or Process Control groups.
Polymer Char instruments are fully automated, including sample preparation. They are designed in a modular way to facilitate maintenance and to use the best components in the industry in order to provide the highest reliability.
The analysis of the Molar Mass Distribution of Polyethylene and Polypropylene resins by GPC / SEC has always been considered a demanding task due to the requirement of high temperature operation for dissolution and multi-detection methods, which results in complex hardware design.
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.
The direct measurement of the two-dimensional distribution by cross-fractionation in terms of both molar mass and chemical composition is the most comprehensive way of obtaining a full definition of the microstructure in Polyolefins.
The Soluble Fraction test is designed to measure the amorphous fraction of polypropylene and ethylene-propylene copolymers. The accuracy and precision of this test are very important to the process and product specifications of the resultant materials.
Polymer Char’s PREP mc2 and PREP C20 are powerful automated instruments to fractionate polymers by composition or molar mass.
IVA is based on Polymer Char's recently developed QC platform, which integrates, in a reduced footprint, a robust dual-capillary relative viscometer combined with a high-temperature autosampler with a capacity for 42 samples.
A complete range of solutions with the recent launch of a line of accessories that aim to facilitate the work done in a polyolefin characterization laboratory.
