Powder calcium zinc stabilizer is a type of stabilizer used in the production of PVC (polyvinyl chloride) products. It is white powder that is added to the PVC resin during the manufacturing process to improve the heat stability and processing characteristics of the material.
Calcium zinc stabilizers are preferred over other types of stabilizers, such as lead-based stabilizers, due to their lower toxicity and environmental friendliness. They are commonly used in various PVC applications, including pipes, fittings, profiles, cables, and films.
The main function of powder calcium zinc stabilizer is to prevent the degradation of PVC during processing and exposure to heat and light. It acts as a heat stabilizer, protecting the PVC from thermal degradation and maintaining its physical properties. Additionally, it helps to improve the melt flow of the PVC resin, making it easier to process and mold.
Powder calcium zinc stabilizer is typically added to the PVC resin in small amount…
