In the plastics and coatings industries, stabilizers play a critical role in ensuring product durability against heat, light, and oxygen. Calcium-zinc (Ca-Zn) stabilizers stand out for their safety and eco-friendliness, replacing traditional lead-based systems. This article explores Ca-Zn stabilizers, compares them to traditional systems, and highlights their practical applications.
WHAT IS A STABILIZER?
Stabilizers are essential chemical compounds in plastics and coatings production, maintaining the physical and chemical properties of products. They prevent polymer degradation caused by heat, light, or oxygen. The two most common stabilizer types are traditional systems and calcium-zinc systems, each offering unique advantages to meet diverse industry needs.
TRADITIONAL STABILIER
Traditional stabilizers, often based on lead or tin compounds, are highly effective in preventing thermal degradation in PVC. They ensure durability, rigidity, and heat resistance, making them suitable for applications like pipes, rigid sheets, and cables.
However, traditional systems pose environmental concerns due to the toxicity of lead, which can harm human health. As a result, manufacturers are shifting toward safer alternatives, paving the way for calcium-zinc stabilizers.

WHAT IS A CALCIUM-ZINC STABILIZER?
Calcium-zinc stabilizers are eco-friendly alternatives using calcium and zinc salts combined with additives. They protect PVC from thermal and UV degradation without relying on toxic heavy metals, meeting stringent international safety standards like REACH and RoHS.
Ca-Zn stabilizers provide excellent color retention and enhance product resistance to aging, extending service life. They are ideal for flexible plastics like packaging films and vinyl flooring. In coatings, they improve adhesion and film durability.

ADVANTAGES OF CALCIUM-ZINC STABILIZER
Ca-Zn stabilizers are free of lead and cadmium, reducing environmental impact and enabling compliance with strict chemical safety regulations. This facilitates exports to global markets.
They offer thermal stability comparable or superior to traditional systems, preventing polymer degradation during processing for consistent, high-quality products. Ca-Zn stabilizers are versatile, suitable for both rigid and flexible PVC applications, including water pipes, cables, films, and vinyl flooring. In coatings, they enhance weather resistance and durability.
While initial costs may be higher than traditional systems, Ca-Zn stabilizers reduce long-term expenses through improved product durability, fewer defects, and compliance with environmental regulations, avoiding potential fines.
APPLICATIONS OF CALCIUM-ZINC STABILIZER
PVC Plastics Production
In plastics, Ca-Zn stabilizers are widely used to produce high-quality products. PVC pipes benefit from excellent mechanical strength and resistance to high pressure and heat. Packaging films maintain transparency and flexibility, while vinyl flooring offers superior abrasion and UV resistance.
Coatings Production
In coatings, Ca-Zn stabilizers enhance film adhesion and resistance to fading from sunlight, ensuring long-lasting aesthetics for outdoor applications. They also minimize peeling, maintaining coating integrity.
WHY CHOOSE CALCIUM-ZINC STABILIZER?
Manufacturers of plastics and coatings should prioritize safe, effective stabilizers. Ca-Zn systems meet both criteria, enhancing brand reputation in global markets by complying with export standards. Their eco-friendliness reflects corporate social responsibility.
Ca-Zn stabilizers optimize production by minimizing defects and reducing maintenance costs. As industries embrace sustainability, Ca-Zn systems offer a strategic, long-term solution.
