Calcium zinc stabilizer and composite lead salt stabilizer refer to PVC heat stabilizers, which play a role in thermal stability in PVC product production. The difference between the two is as follows:
Calcium zinc heat stabilizers meet environmental requirements and are currently widely used. Its characteristics include the following aspects:
1. The most important feature of calcium zinc stabilizers is that they are used in both transparent and opaque product formulations in chemical building materials, with strong applicability.
2. The price is lower than that of organotin.
3. It has good compatibility and coordination with lead, tin, cadmium, and antimony stabilizers, and there is no sulfur pollution. It is suitable for manufacturers who have already used lead salt stabilizers to replace non-toxic and environmentally friendly products.
4. Another significant advantage of calcium zinc stabilizers is their good weather resistance, and products produced with qualified calcium zinc composite stabilizers will not experience discoloration.
The application of lead salt stabilizers has gradually decreased due to their toxicity. Its characteristics are as follows:
1. Toxic.
2. Cannot be used for transparent products.
3. Good electrical insulation and weather resistance;
4. Low price;
5. Good processing performance suitable for various processes;
