In the Artificial Leather Production, heat PVC stabilizers play a crucial role.Effectively suppressing the occurrence of thermal decomposition phenomenon, while accurately controlling the reaction rate to ensure the stability of polymer molecular structure, thus ensuring the smooth progress of the entire production process.
(1)Barium cadmium zinc thermal stabilizer
In the early calendering process, barium cadmium zinc heat stabilizers were commonly used. Barium salts can ensure the stability of materials during long-term high-temperature processing, cadmium salts play a stabilizing role in the middle of processing, and zinc salts can quickly capture the hydrogen chloride produced by PVC degradation at the beginning.
However, due to the toxicity of cadmium, the use of such stabilizers has been subject to many restrictions as environmental requirements become increasingly stringent.
Barium zinc stabilizers, as an important type of heat stabilizer, are widely used in the production of synthetic leather.In coating process, barium zinc stabilizer performs well. In the oven plasticization process, it can prevent the coating from turning yellow and brittle due to high temperature, making the finished artificial leather product bright and durable in color.
(3)Calcium Zinc composite heat stabilizer
Nowadays, calcium zinc composite heat stabilizers have become mainstream. In the calendering process, it can maintain the stability of materials subjected to high-temperature mixing and rolling. Calcium salts bear the responsibility of long-term thermal stability, while zinc salts undergo timely treatment of initial thermal decomposition. Organic additives further enhance the stability effect, resulting in uniform thickness and good performance of artificial leather.
Moreover, due to its environmentally friendly and non-toxic characteristics, it is particularly suitable for fields with high environmental requirements such as children’s toys and artificial leather for food packaging.
TopJoy Chemical focuses on the research and production of PVC stabilizers, and its products have been deeply cultivated in the field of synthetic leather for many years. With excellent thermal stability, good compatibility, and outstanding weather resistance, the quality of synthetic leather is effectively guaranteed, and it performs well in both color durability and physical properties, thus gaining the trust of domestic and foreign customers.
