2025-06-26
Calcium zinc stabilizer, as an important environmentally friendly heat stabilizer, plays a crucial role in the plastic processing industry, especially in the field of PVC products. It is mainly composed of calcium salts, zinc salts, lubricants, antioxidants and other components synthesized through a special composite process. It has excellent thermal stability, photostability, transparency and coloring power, and can effectively replace traditional lead cadmium salts and organotin toxic stabilizers, meeting the requirements of modern industry for environmental protection and safety.
1、 Product Classification and Characteristics
Calcium zinc stabilizers are usually divided into two categories: solid calcium zinc stabilizers and liquid calcium zinc stabilizers. Solid calcium zinc stabilizer appears as a white powder, sheet or paste, and is the most widely used non-toxic PVC stabilizer, commonly used in food packaging, medical equipment, wire and cable materials and other fields. The liquid calcium zinc stabilizer appears as a light yellow oily liquid with high solubility and good dispersibility. It has little effect on transparency, but there is a risk of precipitation, and a suitable solvent needs to be selected.
Calcium zinc stabilizers not only have excellent thermal stability and transparency, but also have toughening and melting promoting effects, making PVC mixtures have good uniform plasticization and high-speed melting flowability, and the surface of the product smooth. In addition, it also has good lubricity and unique coupling effect, which can endow fillers with good dispersibility, enhance encapsulation with resin, improve product performance, reduce mechanical wear, and extend equipment service life.
2、 Application Fields
Calcium zinc stabilizers play an irreplaceable role in the production of PVC and other plastic products. It has a wide range of applications, including but not limited to the following aspects:
Building materials: used for the production of PVC pipes, profiles, fittings, boards and other building materials, providing stable performance support.
Wire and cable: In the wire and cable industry, the application of calcium zinc stabilizers can meet the hygiene requirements of non-toxic and environmentally friendly, while providing excellent thermal stability and resistance to sulfide pollution.
Other plastic products: They are also widely used in the PVC product industry such as soft pipes, granulation, calendering films, toys, conveyor belts, advertising fabrics, wallpapers, etc.
3、 Market Status and Development Trends
With the increasing global awareness of environmental protection and the promotion of environmental policies, the demand for calcium zinc stabilizers in the market continues to grow. It is expected that the global calcium zinc stabilizer market will maintain a stable growth trend in the coming years. At the regional level, the Chinese market has undergone rapid changes in the past few years and has become one of the world's important producers and consumers of calcium zinc stabilizers.
