As an environmentally friendly heat stabilizer, calcium-zinc stabilizers are leading the sustainable development of the PVC wood grain foil industry. This material has become the preferred solution to replace traditional lead salt stabilizers due to its unique advantages.

Core Advantages

1. Environmental characteristics: Completely free of heavy metals such as lead and cadmium, complying with international environmental standards like EU RoHS

2. Thermal stability: Effective working temperature range of 160-210°C, significantly inhibiting PVC decomposition during processing

3. Product performance: Maintains product whiteness >95%, QUV aging test ΔE<3.0, impact strength >6kJ/m²

Process Performance

• Optimized ratio (calcium/zinc=3:1) improves extrusion efficiency by 10-15%

• Melt pressure fluctuation controlled within 5%, ensuring processing stability

• Synergistic effect with β-diketone and other auxiliaries to solve "zinc burning" issues

Technological Innovations

1. Rare earth modification: Extends thermal stabilization time by 50%

2. Functional expansion: Develops special types including antibacterial (antibacterial rate >99%) and high transparency (light transmittance 90%)

3. Nanotechnology: Enhances comprehensive performance through coating modification

Market Status
Currently holding over 85% domestic market share, further breakthroughs are still needed for applications above 200°C and compatibility with recycled materials. With the implementation of new standards like GB/T 3324-2017, calcium-zinc stabilizers will continue to drive the industry's green transformation, providing critical technical support for the sustainable development of PVC wood grain foils.
