Introduction to PVC Mixing Technology In the processing of PVC (polyvinyl chloride), mixing technology is the first crucial step in the production of PVC products and plays a vital role. However, many companies often overlook this step, and workers tend to misunderstand the mixing process, thinking that mixing is simply stirring all components of the formulation evenly. In fact, mixing technology is far more complex…

Common Evaluation Methods for the Stability of PVC Stabilizers Stabilizers are one of the most essential and indispensable materials in PVC products. Unlike the past, where the market was dominated by tribasic lead sulfate, dibasic lead stearate, lead stearate, and barium stearate, today's stabilizers have evolved. Except for transparent products and a few soft products that still use organotin or liquid calcium-zinc-barium-cadmium stabil…

How to Optimize the Ratio of Zinc Stearate and Calcium Stearate in PVC Applications In a calcium-zinc stabilizer system, there are distinct differences in the lubrication behavior between zinc stearate (ZnSt) and calcium stearate (CaSt), which are closely related to their compatibility with PVC during processing, migration rate, and functional stages. Below is an analysis of their lubrication mechanisms and formulation optimization recommendations:1. Lubricatio…
