Hydrotalcite Usage
1.It is an inorganic compound and is a good acid absorbent, which can effectively inhibit zinc burning during processing
2.Good thermal stability at high temperatures, up to 400°C, especially suitable for hard processing formulations
3.When used in combination with St-220, it has a good multiplication effect on heat stability
4.It is suitable for the addition of Ba-Zn and Ca-Zn formulas, and it can reflect its unique effects when applied in Ba-Zn and Ca-Zn rigid formulations
5.Even if the temperature exceeds 350°C, the phenomenon of separation of bubbles such as CO2 and H2O does not occur, so it can be effectively used as a hard PVC stabilizer in high processing temperatures
6.When 5 phr was used alone, the Congo Red time at 200°C reached 183 minutes.
