Standard Test Methods for Powder-Mix Time of Poly(Vinyl Chloride) (PVC) Resins Using a Torque Rheometer

Importancia y uso:

5.1 The ability of PVC granules to accept a plasticizer and become a dry free-flowing powder is related to the internal pore structure of the resin, resin temperature, plasticizer temperature, and the plasticizer used. By choosing an applicable plasticizer and maintaining a uniform temperature for the resin and plasticizer, it is possible to classify resins by how rapidly they absorb plasticizer. Resin suitability for a specific intensive mixing operation can be ascertained using these test methods.
