Differences between calcium zinc stabilizer and lead salt stabilizer

Lead salt stabilizer: good thermal stability; Good weather resistance and electrical insulation; The cost is lower than that of calcium zinc stabilizer; Suitable for various processing technologies. The main disadvantage of lead salt stabilizer is that it is toxic. A small amount of lead may combine with sulfur in the air to produce toxic substances. And the color image is relatively poor, so lead salt stabilizer cannot be used for transparent plastic products.

Calcium zinc stabilizer: white powder, non-toxic and harmless; It will not cause pollution like lead salt stabilizer; Very good adaptability, able to blend with a variety of materials and maintain stability; The addition amount is relatively small, reducing the use cost. In addition to the role of stabilizer, calcium zinc stabilizer can also shorten the plasticizing time and promote plasticization.
