Lianfu is a leading PVC CAZN STABILIZER manufacturer, providing the highest quality non-toxic, heavy metal-free CAZN Stabilizer. Calcium zinc stabilizer is very common in various PVC applications. It is widely used in flexible and rigid PVC applications. Calcium zinc stabilizer is composed of calcium salt, zinc salt, lubricant, antioxidant, etc. It can not only replace toxic stabilizers such as lead, cadmium salt, tin, but also has good thermal stability, light stability, transparency and colorability. In the production of PVC products, it has good processing performance and thermal stability equivalent to lead salt stabilizer. It is an excellent non-toxic stabilizer.
Formulation adjustment: In order to achieve optimal performance, calcium zinc stabilizers usually need to be used in combination with other auxiliary stabilizers (such as antioxidants) and additives to make up for some of their performance deficiencies, which may increase the complexity of the formula.
Compatibility and dispersibility: Although calcium zinc stabilizers have good compatibility with PVC, in actual applications, it is still necessary to ensure that they are evenly dispersed in the polymer to avoid product quality problems caused by uneven dispersion.
Calcium zinc stabilizer for PVC is typically supplied in different physical forms to meet diverse processing requirements:
Powder type CAZN stabilizer (for extrusion and compounding)
Granule type stabilizer (for improved dosing and mixing accuracy)
One-pack stabilizer systems (pre-formulated with lubricants and additives)
Customized formulations for rigid or flexible PVC applications
Its multi-component formulation ensures stable processing performance by integrating heat stabilizers, antioxidants, and lubricants into a single efficient system.
1. Environmentally friendly & non-toxic
CAZN stabilizers contain no lead, cadmium, or other heavy metals, making them suitable for environmentally sensitive applications such as food contact materials, medical products, and children’s goods.
2. Excellent thermal stability
Through advanced formulation design, calcium zinc stabilizers provide reliable heat resistance during PVC processing such as extrusion, injection molding, and calendaring, ensuring stable product quality.
3. Good transparency & color performance
Ideal for transparent or semi-transparent PVC products, the stabilizer maintains optical clarity and enhances color consistency without yellowing.
4. Improved processing performance
It enhances melt flow stability, reduces plate-out, and minimizes processing issues such as sticking to molds or uneven dispersion, improving production efficiency.
5. Strong weather resistance
Calcium zinc stabilizers improve UV resistance and outdoor durability, extending the service life of PVC products exposed to sunlight and environmental stress.
Calcium zinc stabilizer for PVC is widely used across multiple industries, including:
Food packaging film and sheets
Medical tubes and medical-grade PVC products
Children’s toys and consumer goods
Electrical wiring and cable insulation
Artificial leather and synthetic materials
Automotive interior components
Flexible and rigid PVC profiles and films
