Liquid Barium Zinc Ba/Zn PVC Stabilizer

Product Overview

Liquid Barium Zinc Stabilizer is a high-efficiency composite metal heat stabilizer specially formulated for soft and semi-rigid PVC processing. It is compounded with organic barium salts, organic zinc salts, high-performance chelating agents, antioxidants and lubricants through precise formulation design, appearing as a light yellow to amber clear oily liquid. With excellent synergistic stabilization effect, it delivers balanced performance in thermal stability, weathering resistance and transparency.

Key Specifications

Core Features

1. ‌Superior Thermal Stability Performance‌: Excellent synergistic effect between barium and zinc components, effectively suppresses PVC dehydrochlorination reaction, delivers low initial coloring, long-term thermal aging resistance and no sudden blackening phenomenon.

2. ‌Excellent Weathering & Sulfide Staining Resistance‌: Effectively isolates the contact between zinc ions and external sulfide, prevents finished products from discoloring during long-term outdoor use, and maintains stable appearance performance.

3. ‌High Transparency & Compatibility‌: Matches the refractive index of PVC system well, helps transparent soft PVC products achieve low haze and uniform color, fully dissolves in common plasticizers with excellent dispersibility, no precipitation or blooming risk.

4. ‌Low Dosage & High Efficiency‌: Recommended addition level is only 2-3 phr, far lower than ordinary solid composite stabilizers, effectively reduces formulation cost and avoids dust pollution on production site.

5. ‌Wide Processing Adaptability‌: Suitable for calendering, extrusion, blow molding and plastisol processing technologies, no negative interaction with common PVC additives such as epoxidized soybean oil, phosphite esters and lubricants.

Recommended Applications

· PVC calendered transparent films, white and light-colored soft products

· PVC artificial leather, PVC coated fabric, wallpaper and calendered foaming layers

· PVC soft hoses, sealing strips, electrical insulation parts and extrusion soft profiles

· PVC plastisol products, toys, gloves and all kinds of soft PVC processing scenarios

Suggested Dosage

For general calendered PVC film and artificial leather applications, the recommended addition level is 2.0 - 2.5 phr per 100 parts of PVC resin. For high-demand transparent products and foaming layer scenarios, the dosage can be adjusted to 2.5 - 3.0 phr. It is recommended to conduct small-scale formulation tests on your own production line to confirm the optimal loading amount.
