SODIUM HYDROXIDE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Hydroxide, also known as caustic soda or lye (NaOH), is a white, crystalline inorganic compound used in various industrial and chemical applications as a strong base and alkali. It is commonly employed in the production of paper, textiles, and detergents, where it acts as a strong base to neutralize acids and saponify fats and oils. Sodium Hydroxide is also used in the manufacture of aluminum, soaps, and other chemicals. In water treatment, it is used to adjust pH levels and remove impurities. Proper handling and storage of Sodium Hydroxide are essential to prevent accidents and ensure safety, as it is highly corrosive and can cause severe burns upon contact with skin or eyes. Proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential when working with Sodium Hydroxide. Its versatility and effectiveness as a strong base make it a valuable chemical in numerous industrial and chemical applications.
