by Technique

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.

Molar Mass Distribution

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

Bivariate Distribution

Soluble Fraction

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.

Preparative Fractionation
