Stearic Acid
Stearic Acid (CAS: 57-11-4) is a saturated fatty acid critical for the PVC and rubber industries. It functions as an excellent lubricant, significantly improving processing efficiency and the surface quality of end products. Its role as a thermal stabilizer is vital, preventing degradation during high-temperature manufacturing processes, thereby ensuring product integrity and longevity. Additionally, it acts as an effective anti-sticking agent and a synergist for plasticizers, enhancing flexibility and ease of mold release. Derived from natural sources, it offers a cost-effective and environmentally friendly solution for various industrial applications.
- Enhance your PVC processing efficiency with superior stearic acid lubrication, ensuring smoother material flow and preventing sticking to equipment.
- Achieve better light and heat stability in your PVC products by utilizing stearic acid as an effective PVC heat stabilizer.
- Improve the flexibility and mold release of your plastic formulations with the synergistic effects of stearic acid plasticizer synergy.
- Prevent scorching and discoloration in PVC products by leveraging the anti-sticking and stabilizing properties of industrial grade stearic acid applications.
