Our sodium silicates are used extensively in hydrogen peroxide bleaching of both virgin fiber and recycled fiber. They stabilise peroxide by binding transition metals such as iron, copper and manganese, which would otherwise catalyse premature oxygen release. In deinking of wastepaper, the soil suspending properties of our sodium silicates aid the removal of ink particles from the paper fiber.

Our sodium silicates are an important component in hydrogen bleach liquors. In this function, our silicates help to stabilize the peroxide resulting in a brighter pulp at a lower cost. In addition, our silicates buffer the bleach liquor at the pH at which the peroxide is most effective.
Our sodium silicates help remove inks from the paper surface and enhance dispersion which prevents the ink particles from redepositing on the fibers.
