Sodium hydroxide, also known as lye or caustic soda (NaOH)

Sodium hydroxide is a highly caustic base and alkali, used in many industries in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner.
Sodium hydroxide may cause chemical burns and may induce permanent blindness upon contact with eyes and must be handled in a safe and responsible manner.

Wetted parts in CFRETFE are particular suitable for sodium hydroxide.
