Acrylic Impact Modifiers for PVC: Core-shell modifier chemistry and performance
Raber Inoubli, July 2021
Part 2 of the All Things PVC Workshop series. The speaker will review the basics of core-shell chemistry focusing on acrylic technology and its advantages for mechanical property improvement and weatherability in PVC formulating. Core principles of mechanical property improvement via stress concentrators for PVC matrices and formulations will be presented. In addition to rheology and mechanical property enhancement via acrylic chemistry, the presentation will also provide perspective on choosing the best impact modifier based on specific formulation needs or application types where standards vary based on the final needs of the vinyl building product, for example. The talk will follow-up on the principles covered in the introduction to PVC Gelation and Formulation.

Non-Tin Heat Stabilizers for Clear rigid PVC Applications
Masumi Mizu | Taro Mitsudera | Tadashi Sengoku | Kiyotatsu Iwanami | Toshinori Yukino | Hiroshi Nishimura | Robert G. Weiler, September 2010
The purpose of this paper is to describe the development of a new class of Calcium/Zinc heat stabilizer for clear rigid PVC applications. Typically, until this time, Organo-Tin based heat stabilizers have been used for this application. Organo-Tin heat stabilizers offer excellent transparency and good heat stability protection. Recently, Butyl-Tin based heat stabilizers have been designated as an environmental Substance of Very High Concern (SVHC) in EU. This has led us to research and develop alternative heat stabilizers for clear rigid PVC applications. Liquid Barium/Zinc based heat stabilizers offer good transparency but they typically do not have enough heat stability under rigid PVC processing conditions. They also have the environmental problem of the heavy metal, Barium. Typical Calcium/Zn stabilizers have good heat stability, and are environmentally more acceptable, but typically are deficient in transparency. Our purpose in this paper is to describe a technique for selecting individual components for a high transparency powder Calcium/Zinc heat stabilizer and to demonstrate that the transparency and heat stability are suitable for the task of protecting clear rigid PVC applications. Three important technical points necessary for improving transparency were described. First is refraction (Refractive index). Second is scattering (particle size). And third is dispersion (compatibility). Ideal state satisfied these three points.

Fire Performance Synergies of Metal Hydroxides and Metal Molybdates in Antimony-Free Flexible PVC
Ken Walker | Alex Isarov | Tong Chen, September 2010
Viability of continued use of antimony oxide is among the topics of broad interest to PVC compound suppliers as well as their end users. Existing and emerging regulatory mandates have continued to drive an industry-wide effort to minimize use of antimony oxide in PVC, while being able to maintain adequate fire performance when formulating the low-smoke compounds for a variety of applications such as construction materials and wire and cable products.
