Calcium zinc stabilizers, as an ideal alternative to lead salt stabilizers, have the following comprehensive advantages:
1、 Environmental Protection and Safety
No heavy metal pollution
Calcium zinc stabilizers do not contain toxic metal elements such as lead, chromium, tin, barium, etc., and comply with international environmental standards (such as the EU RHOS directive and REACH directive), which can avoid lead salt pollution problems.
Green production
The product is biodegradable and environmentally friendly, complying with national environmental policies and reducing pollution risks during the production process.
2、 Performance improvement
thermal stability
Has excellent long-term heat resistance, with thermal stability close to that of lead salt stabilizers, reducing the number of mold disassembly and downtime during high-temperature processing, and improving production efficiency.
Optimization of processing performance
Reduce processing temperature and power consumption, shorten plasticizing time, and decrease the amount of regulator used.
Improve liquidity, increase extrusion speed and output, and reduce energy consumption.
Lubrication and antioxidant properties
Enhance the lubricity of PVC resin and reduce friction loss; Improved antioxidant performance and extended product lifespan.
3、 Cost and compatibility
Cost effectiveness
Lightweight (about 40% lower density), more inorganic fillers can be added to reduce costs; High safety of raw materials reduces additional processing costs caused by heavy metal pollution.
System switching friendly
Good compatibility with lead salt stabilizers, no need to worry about cross contamination when replacing, reducing production system adjustment costs.
4、 Other advantages
Sulfur resistant pollution: When used in sulfur-containing coal areas (such as some northern regions), it will not produce acid rain or blackening like lead salt stabilizers.
Transparency: Some products maintain good transparency to meet aesthetic requirements.
In summary, calcium zinc stabilizers have become the preferred material for PVC product processing due to their comprehensive advantages in environmental protection, safety, performance, and cost.
