Additional information
| Significance and Use | ||||||
|
When PVC compounds are mixed under appropriate conditions of heat and shear, a fused mass is produced. This mass has certain melt characteristics which can be defined with a torque rheometer operated under fixed conditions of shear and temperature. The fusion characteristics of a PVC compound are manifest as fusion time, fusion torque, melt torque, melt viscosity, and heat and color stability. A control lot is to be used as a standard against which other test results are to be compared. Test data are to be evaluated relative to the control lot. |
