Polymer analysis is used not only for product quality control, but also for monitoring physical properties during production such as stiffness, transparency and gloss.

Analyze Determination of Xylene Soluble in Polypropylene

The determination of soluble in xylene in polypropylene is a fundamental parameter for quality control of the products of a polymer industry. Xylene soluble is the expression of a parameter established based on the percentage (%) of soluble substances in polypropylene, polyethylene, and other homopolymers and copolymers.  

With conventional methods it can take hours, but with SpecFIT this type of analysis is performed in seconds and with accurate results. Calibration is performed with 3 to 6 samples and can be performed on samples in pellet or sphere format.
