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.
Traditionally, the Soluble Fraction analysis is done by using the gravimetric method, which requires manual operation along the whole process. As a result, the precision is poor and the procedure is time consuming.
Polymer Char’s CRYSTEX, CRYSTEX QC, and CRYSTEX 42 automate this method while obtaining higher precision and accuracy in the results as well as avoiding manual solvents handling.
