Scope of Application
Q: What is powder barium zinc PVC stabilizer?
A: Powder barium zinc stabilizer is a composite heat stabilizer used in PVC processing. It improves thermal stability, durability, and processing performance.
Q: What are the key advantages of powder Ba Zn stabilizer?
A: It offers excellent heat stability, good lubricity, and strong weather resistance. It also provides good dispersion and stable processing performance.
Q: What applications are suitable for powder Ba Zn stabilizers?
A: It is widely used in flexible and semi-rigid PVC products such as films, artificial leather, cables, and coated fabrics. It is suitable for calendering and extrusion processes.
Q: What is the recommended dosage of powder Ba Zn stabilizer?
A: The typical dosage is 6–8 phr, depending on formulation and processing conditions. Higher dosage may be required for demanding applications.
Q: How does Ba Zn stabilizer improve PVC stability?
A: Barium compounds neutralize HCl released during PVC degradation, while zinc compounds help prevent discoloration. This synergistic effect improves long-term stability.
Q: What is the difference between powder and liquid Ba Zn stabilizers?
A: Powder stabilizers are suitable for dry blending and easier storage, while liquid stabilizers offer better dispersion in plastisol systems. Powder types are often preferred for cost-effective production.
