SODIUM POLYACRYLATE WATER ABSORPTION<\/h2>\r\n\r\n\r\n\r\n

As indicated in the table, sodium polyacrylate absorbs more than 80 grams of water per gram of polyacrylate for water of salinity 0.2%, which corresponds to normal tap water.\u00a0<\/p>\r\n\r\n\r\n\r\n

As it absorbs water it acquires the texture of a gel, solid enough to be kept inside a container when turned upside down, but easily mouldable. You can play with the texture of the gel by adding more or less water. The less water you add to the sodium polyacrylate, the drier the texture. For 40 grams water\/1 gram sodium polyacrylate, you will get a snow-like texture. Sodium polyacrylate is used as a base for making decorative artificial snow for this purpose. In Alquera we have a sodium polyacrylate based product for this purpose:\u00a0artificial snow<\/a>.\u00a0<\/p>\r\n\r\n\r\n\r\n
