Scope of Application
Q: What is liquid calcium zinc PVC stabilizer?
A: Liquid calcium zinc PVC stabilizer is a non-toxic heat stabilizer composed of calcium and zinc compounds. It is used to prevent thermal degradation of PVC during processing by neutralizing HCl and improving color stability and durability.
Q: What are the advantages of liquid Ca Zn stabilizer compared to powder stabilizers?
A: Liquid Ca Zn stabilizers offer better dispersion, improved transparency, and easier processing compared to powder stabilizers. They are especially suitable for flexible and semi-rigid PVC applications where high clarity is required.
Q: What applications are suitable for liquid calcium zinc stabilizers?
A: TopJoy liuquid Ca Zn stabilizer are recommended to use in soft PVC prodcuts, the main application:
• Transparent films
• Artificial leather
• PVC hoses
• PVC sheet
• Medical products
• Food packaging
These applications typically require good transparency and high plasticizer content.
Q: What is the recommended dosage of liquid Ca Zn stabilizer?
A: The typical dosage is 2–3 phr, depending on formulation, processing temperature, and product requirements. Adjustments may be needed based on plasticizer content and processing conditions.
Q: Can liquid Ca Zn stabilizer replace lead or tin stabilizers?
A: Yes. Liquid calcium zinc stabilizers are widely used as environmentally friendly alternatives to lead and organotin stabilizers, offering comparable performance while being non-toxic and compliant with global regulations.
Q: Why is liquid stabilizer mainly used in flexible PVC?
A: Liquid stabilizers are more compatible with systems containing higher levels of plasticizers (typically above 30 phr), making them ideal for flexible PVC formulations.
Q: How to prevent precipitation or stability issues in liquid stabilizers?
A: To avoid precipitation:
• Use compatible plasticizers or solvents
• Ensure proper formulation balance
• Store under recommended conditions
Proper formulation design is critical to maintaining long-term stability.
Q: Do you provide free samples for testing?
A: Sure, we recommend to do a test before formal order. Little free samples could be sent as request, but the freight cost should be paid by the consignee.
Q: How to choose the right liquid calcium zinc stabilizer for your application?
A: Contact our sales and tell us more details about your requirement, such as
• Application type (e.g., artificial leather, film, hose)
• Processing method (calendering, coating, extrusion)
• Plasticizer content and formulation system
• Transparency and thermal stability requirements
• Target price
Our team will give you the best recommendation accordingly.
Q: Can you provide customized liquid Ca Zn stabilizer formulations?
A: Sure, we manufacturer PVC stabilizer since 1992 and only focus on this PVC industry. We are happy to help our clients to solve the problems. Customized solutions help improve product quality and production efficiency.
