PVC stabilizers

PVC stabilizersVinyl thermoplasticsProducts

PVC stabilizers are chemical additives that prevents the decomposition of PVC due to heat exposure, protecting it during processing and extending the service life of the final product. They are essential for the production of a wide range of PVC materials such as tarpaulins, electrical cables, profiles, pipes, flooring, etc. The choice of stabilizer depends on the type of PVC (rigid or flexible), the processing method, and the technical specifications of the final product.

 

Importance and fuction

 

        • Thermal protection: Stabilizers prevent PVC degradation when exposed to high temperatures during processing operations such as extrusion, injection molding, or calendering.

        • Long-term stability: They provide greater heat resistance to the final product, ensuring long-term durability.

        • Versatility: They can be used in different types of PVC—both rigid and flexible—depending on the formulation and application.

 

Type of Stabilizers

 

        • Metal-based: Historically, lead-based stabilizers were widely used. Nowadays, other metallic salt blends (such as calcium-zinc stabilizers) are increasingly used due to environmental and health concerns.

        • Organic: Although their individual effect is generally weak, organic compounds can be used as co-stabilizers in combination with primary metal salt-based stabilizers.

        • Commercial products: Various ranges of stabilizers are available on the market, including those that incorporate lubricants and other additives to provide customized solutions for PVC processing.
