Analysis and Characteristics of Caustic Soda Component of PVC Blister Roll Catalyst

Caustic soda is also called sodium hydroxide, the molecular formula is NaOH, and it is one of the common plastic catalysts. Pure sodium hydroxide is composed of a sodium, hydrogen, and oxygen, with a density of 1.988 g/cm3, a boiling point of 1288NaOH, and a melting point of 317.9 °C. Caustic soda is actually a mixture. Edible alkali contains a small amount of magnesium sulfate and sodium chloride. It is an opaque crystal and appears white. In addition to being edible, sodium hydroxide can also be used as a cleaning agent, dissolving grease, dirt and ethanol, and reacting with acids to produce sodium chloride and hydrogen oxide.
