As the most important environmentally friendly heat stabilizer in modern PVC processing, calcium-zinc stabilizers play a critical role in cabinet panel production. Their main components typically include a composite system of calcium stearate, zinc stearate, and various auxiliary stabilizers and lubricants.

Core Functions:

1. Thermal Stabilization Protection

• Neutralizes HCl produced during PVC decomposition through synergistic effects of metal soaps

• Effectively inhibits "zinc burning" phenomenon during processing

• Maintains melt stability within a processing temperature range of 160-210°C

2. Processing Performance Optimization

• Provides balanced internal/external lubrication

• Improves material plasticization performance

• Reduces equipment wear and energy consumption

3. Environmental Safety Assurance

• Completely free of heavy metals like lead and cadmium

• Complies with EU RoHS, REACH and other environmental regulations

• Meets toy safety standards like EN71-3

4. Product Performance Enhancement

• Maintains long-term product stability

• Reduces risk of post-production discoloration

• Shows good compatibility with foaming systems

Market Application Status:
With increasingly stringent environmental regulations, calcium-zinc stabilizers have become standard in PVC cabinet panels in European and American markets, while their penetration continues to increase in China's high-end cabinet panel market. The latest developed composite calcium-zinc stabilizers, through special additive formulations, now approach the thermal stabilization efficiency of traditional lead salt stabilizers.

Future Development Trends:

1. High Performance: Developing formulations with higher thermal stabilization efficiency

2. Functional Integration: Combining multiple functions like lubrication and oxidation resistance

3. Cost Optimization: Reducing production costs through new processes

4. Specialization: Developing specialized models for different cabinet panel requirements

Selection Recommendations:
Cabinet panel manufacturers should select appropriate calcium-zinc stabilizer models based on specific formulations, equipment conditions and product requirements, and may seek customized solutions from suppliers when necessary.
