PVC Ca-Zn stabilizers are essential additives used in PVC formulations to enhance the material's resistance to light, weather, and heat aging. By incorporating these stabilizers into the PVC matrix, they help prevent degradation caused by exposure to external factors such as UV radiation, temperature fluctuations, and atmospheric conditions.  The Ca-Zn stabilizers act as sacrificial agents that absorb harmful free radicals generated during the degradation process, thus preserving the structural integrity and performance of PVC products over time.  This increased stability not only ensures prolonged durability but also maintains the aesthetic appeal of PVC materials by reducing discolorationand brittleness.  Ultimately, the use of PVC Ca-Zn stabilizers in formulation results in a more reliable and long-lasting product that can withstand harsh environmental conditions with minimal deterioration.    More information and samples will be provided.
