In the production of PVC products, a processing aid is a polymeric additive that regulates the processing behavior of the PVC system. The effect of a processing aid is directly reflected in parameters such as fusion behavior, melt homogeneity, rheological stability, and surface quality of the final product.

Engineering Guide to Wax Selection in PVC An Engineering Comparison of PE Wax, Paraffin Wax, and Fischer–Tropsch Wax Introduction Wax selection in PVC formulation is not merely an economic decision; it is an engineering choice that directly affects process stability, surface quality, fusion behavior, and production repeatability.
