The processing range of Ca Zn stabilizer is narrow, and the processing requirements must be strictly implemented. Compared with the traditional composite lead heat stabilizer, the long-term heat resistance stability of the Ca Zn heat stabilizer is still relatively poor. The residence time is longer during processing, it is easy to yellow, and the sensitivity to the process temperature is also higher.
The Ca Zn stabilizer have a high volatile content. It is recommended to use a lubricant with a high melting point and low volatility in the formulation.
Compared with the traditional composite lead heat stabilizer, the Ca Zn heat stabilizer has a high content of organic matter, which is likely to cause the precipitation to be too large, and the choice of lubricant needs to be more cautious.
Ester lubricants can balance the fluidity and mold release effectively during plastic processing.They have a long production cycle and are not easy to precipitate.In addition, they can be used widely in the formulation of Ca Zn stabilizer.
