Scope of Application
Q: What is paste calcium zinc PVC stabilizer?
A: Paste calcium zinc stabilizer is a Ca-Zn stabilizer in paste form designed for PVC plastisol (paste) systems. It provides thermal stability and ensures good compatibility with plasticizers.
Q: What are the advantages of paste Ca-Zn stabilizer?
A: It offers excellent dispersion, good transparency, and stable viscosity. It is ideal for applications requiring smooth processing and uniform coating.
Q: What applications are suitable for paste Ca-Zn stabilizers?
A: It is widely used in soft PVC paste applications such as artificial leather, gloves, and medical PVC products.
Q: What is the recommended dosage of paste Ca-Zn stabilizer?
A: The typical dosage is 2–3 phr, depending on formulation and processing conditions. Adjustments may be needed based on plastisol viscosity and product requirements.
Q: Why is paste stabilizer used in PVC plastisol systems?
A: Paste stabilizers provide better compatibility with liquid plasticizers and ensure uniform mixing. This helps maintain stable viscosity and consistent product quality.
Q: What is the difference between paste and powder Ca-Zn stabilizers?
A: Paste stabilizers are designed for liquid/plastisol systems with better compatibility and dispersion. Powder stabilizers are mainly used in dry blending for rigid PVC.
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: Is paste Ca-Zn stabilizer environmentally friendly?
A: Yes, it is lead-free and suitable for environmentally friendly formulations. It is widely used in applications with safety and compliance requirements.
Q: How to choose the right paste Ca-Zn stabilizer?
A: Selection depends on application type, viscosity requirements, and processing method. Paste stabilizers are ideal for coating, dipping, and foam plastisol systems.
★ We can recommend suitable models based on your formulation.
Q: Can you provide customized paste Ca-Zn stabilizers?
A: Yes, formulations can be tailored for viscosity control, heat stability, and processing performance. Customized solutions help improve product quality and efficiency.
