PVC COMPOUNDING PROCESSING
· CPVC has a glass transition temperature approximately 50 higher than PVC but also has a higher melt viscosity in processing. The upper service temperature for CPVC is approximately 100 °C in comparison to PVC at 60 °C. Pipe moldings and sheet are formulated for high-temperature use based on CPVC or blends of CPVC and PVC.

The mixing process initiates shear. As the temperature builds up this helps disperse many of the ingredients. When all the materials have been thoroughly blended together the shear forces start to reduce again and the compound is formed. The compound then exits the mixer as a spherical mass and is transferred on to a two-roll mill.
