Introduction to PVC gelation and formulation with Kevin Yocca

While introducing the general properties of PVC suspension resin that make it unique for processors, Kevin Yocca discusses why PVC formulations can get complicated and presents so many options for optimized processing and customization by application.

The focus revolves around suspension PVC for rigid vinyl applications but touches upon some basics of plasticized or flexible vinyl as well. Kevin talks about gelation theory, why lubricant balance is important, and how different additives can influence rheology, mechanical performance, and even weatherability. This talk is an introduction to PVC overall but also a lead-in for the next workshop, an introduction to acrylic impact modifiers and core-shell modifier chemistry.
