PELS Anhydrous Caustic Beads is a form of dry caustic soda beads. The tiny, white spherical beads offer superior properties: little or no dust, excellent flow properties, uniform size, excellent blending characteristics, structural strength, high bulk density and low moisture pickup, resulting in less caking or lumping. Also known as sodium hydroxide beads and lye. Our bulk caustic soda beads are great for medium to large scale soap manufacturing.
