Performance Mapping toward Optimal Addition Levels and Processing Conditions for Different Types of Hydrocarbon Waxes Typically Used as External Lubricants in Sn-Stabilized PVC Pipe Formulations.

The mechanism of performance of hydrocarbon waxes used as external lubricants in typical PVC pipe formulations is not completely understood or defined. This study will benefit pipe manufacturers to tailor PVC processing conditions and wax addition levels to enhance the value of waxes with different molecular architectures in Sn-stabilized PVC formulations. A selection of waxes was comprehensively analyzed to understand how their structural and morphological differences impact the fusion behavior of a Sn-stabilized PVC compound.
