The Role of Pvc Calcium-Zinc Stabilizer

2023-05-05
PVC calcium-zinc stabilizer (polyvinyl chloride calcium-zinc stabilizer) is an additive widely used in the processing of polyvinyl chloride (PVC) products. It is mainly used to stabilize the thermal stability of PVC materials during high-temperature processing and long-term use to prevent material degradation and fading.
PVC calcium-zinc stabilizer plays several important roles in the processing and use of PVC products:
1. Heat stability: PVC is easy to decompose at high temperatures, resulting in color change, quality reduction and even loss of original performance. PVC calcium-zinc stabilizer can improve the thermal stability of PVC materials, reduce the occurrence of decomposition reactions, and prolong the service life of materials.
2. UV resistance and weather resistance: When PVC products are exposed to outdoor environments, they will be affected by factors such as ultraviolet rays, oxidation, humidity, etc., resulting in the aging and fading of the material. PVC calcium-zinc stabilizer has good weather resistance, which can protect PVC products from ultraviolet rays and oxidation, delay the aging process, and keep the appearance and performance of the material stable.
3. Degradation inhibition: PVC products may come into contact with harmful substances during use, such as acid, alkali, salt, etc. These substances may cause the degradation reaction of PVC, resulting in the decline of material properties. PVC calcium-zinc stabilizer can react with these harmful substances, prevent the degradation reaction, and protect the performance and structural integrity of PVC products.
4. Metal ion neutralization: Calcium and zinc ions in PVC calcium-zinc stabilizer can interact with harmful metal ions in PVC materials, neutralize their impact on PVC, and reduce the toxicity and harm of materials.
5. Increase processing performance: PVC calcium-zinc stabilizer can improve the fluidity and processing performance of the material during the processing of PVC, making the molding of PVC products easier and more stable.
