Compared to traditional calcium/zinc soap-based stabilizers, Calcium Acetylacetonate exhibits superior thermal stability and non-toxicity, making it more cost-effective in practical applications. Especially for rigid PVC products, Calcium Acetylacetonate can significantly improve initial coloration and long-term thermal stability, promote PVC plasticization, and increase the smoothness and brightness of product surfaces. This achieves a balance between environmental benefits and product quality without compromising on either.
