Derived from stearic acid, calcium stearate and zinc stearate are essential for molding and good finishes in products like plastics, rubber, and cosmetics. Despite their similar appearances, each plays a distinct role in different applications. Choosing the wrong one can lead to poor surface quality, reduced cycle times, or regulatory challenges. In this guide, TLD Vietnam explains the key differences between Calcium Stearate vs Zinc Stearate to help manufacturers make informed decisions. Calcium Stearate vs Zinc Stearate: Basic Chemical Overview  Both calcium stearate and zinc stearate are metallic salts derived from stearic acid, a saturated fatty acid commonly obtained from

PVC’s thermal sensitivity, high melt viscosity, and tendency to stick to processing equipment necessitate specialized solutions for smooth and efficient processing. Lubricants play a vital role in addressing these challenges, improving both the performance and quality of PVC products. We have consistently highlighted the importance of lubricants in PVC applications. However, with numerous lubricant options available, PVC manufacturers may find the selection process complex. Choosing the right lubricant requires careful evaluation beyond personal preference to ensure optimal performance and efficiency.  In this blog, our goal is to guide PVC manufacturers through the key considerations for selecting the most suitable lubricant
