Liquid Ba/Cd/Zn PVC Stabilizer

Product Overview

Liquid Barium-Cadmium-Zinc (Ba/Cd/Zn) Stabilizer is a high-performance multi-metal complex heat stabilizer specifically designed for soft and semi-rigid PVC calendering and extrusion applications. As a mature and highly cost-effective stabilizer system, it features an optimal synergistic balance among barium, cadmium and zinc components, delivering outstanding initial color, long-term thermal stability, excellent weathering resistance and sulfide stain resistance. It appears as a light yellow to amber clear liquid, widely recognized in the global PVC industry for its robust performance in transparent, white and light-colored flexible PVC products.

Key Specifications

Core Features

1. ‌Outstanding Initial Color & Long-Term Stability‌: The synergistic effect of barium and cadmium ensures excellent whiteness and clarity from the start of processing, while zinc components effectively delay long-term degradation, preventing yellowing and blackening during extended production runs.

2. ‌Superior Sulfide Staining Resistance‌: The unique formulation design effectively blocks the reaction between zinc ions and external sulfide sources, preventing finished products from discoloring to dark brown or black during long-term storage or use in sulfur-containing environments.

3. ‌Excellent Weathering & Light Stability‌: Provides superior protection against UV radiation and atmospheric oxidation, ensuring the color and mechanical properties of PVC products remain stable even after prolonged outdoor exposure.

4. ‌Wide Processing Adaptability‌: Suitable for all major PVC processing methods including calendering, extrusion, blow molding and plastisol dipping, and shows excellent compatibility with common plasticizers, epoxidized oils and phosphite co-stabilizers.

5. ‌High Cost Performance‌: Delivers premium stabilizer performance at a competitive price point, making it an ideal choice for large-volume production of general-purpose flexible PVC products where cost control is critical.

Recommended Applications

· PVC calendered films, transparent and white soft sheets

· PVC artificial leather, coated fabrics, wall coverings and flooring top layers

· PVC soft hoses, sealing profiles, inflatable products and general extrusion profiles

(Note: Not suitable for products intended for food contact, children's toys or applications with strict heavy metal restrictions.)

Suggested Dosage

For general calendered PVC film and artificial leather applications, the recommended addition level is 2.0 - 3.0 phr per 100 parts of PVC resin. For high-demand transparent products, the dosage can be adjusted to 2.5 - 3.5 phr. It is recommended to combine with 1-2 phr of epoxidized soybean oil (ESBO) and 0.3-0.5 phr of phosphite ester to achieve optimal thermal and light stability performance.
