Abstract
AbstractPVC pipe compounds typically contain varying amounts and types of calcium carbonates, paraffin waxes, and other ingredients such as stabilizers, titanium dioxide, calcium stearate, and processing aids. The purpose of this paper is to study the effect of calcium carbonate particle size, coating, and usage level on the properties of PVC pipe. In addition, the effects of varying the paraffin wax level and melt temperature will be explored. The paper describes these effects as a function of both impact strength and stress‐rupture regression. Based on these results, a series of recommendations on type and usage level of the calcium carbonates and paraffin waxes, and processing conditions for the compound will be developed for use in guiding the pipe manufacturer towards producing PVC pipe that is both performance‐oriented and cost‐effective.
