The Dual Power of Calcium Stearate: Lubrication and Heat Stability in PVC
In the realm of polymer processing, few additives offer the combined benefits of calcium stearate for Polyvinyl Chloride (PVC). As a trusted supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. highlights the indispensable dual roles of calcium stearate: providing essential lubrication and crucial heat stability.
The processing of PVC often involves high temperatures, which can lead to thermal degradation. This degradation is exacerbated by the release of hydrochloric acid (HCl), which acts as a catalyst for further decomposition. Calcium stearate effectively acts as an acid scavenger, neutralizing this HCl and protecting the PVC polymer chains. This function is a core part of its role as a PVC heat stabilizer. By understanding how calcium stearate works in PVC, manufacturers can prevent discoloration and maintain the material's integrity.
Furthermore, calcium stearate is an excellent lubricant for PVC. It functions as both an internal lubricant, reducing friction between polymer molecules to improve melt flow, and an external lubricant, preventing the PVC melt from sticking to processing machinery like extruders and molds. This dual lubrication significantly improves processing efficiency, reduces energy consumption, and enhances the surface finish of PVC products. These are significant benefits of calcium stearate in plastics.
For companies looking to buy calcium stearate, the advantages are clear: improved processability, enhanced product quality, and better manufacturing economics. NINGBO INNO PHARMCHEM CO.,LTD. provides premium-grade calcium stearate that ensures consistent performance across a wide range of PVC applications, including pipes, profiles, films, and cables.
