Product Description
We are suppliers of Gypsum Board Starch plays an important role in the manufacture of gypsum wallboard, protecting the gypsum crystals that form the bond between the gypsum core and the paper. These crystals, located at the edges of the wallboard, are subject to dehydration and breakage during high temperature exposure in the drying kilns. The starch holds water during kiln drying and protects these bonding crystals from dehydration. Severe dehydration causes the paper to peel off of the board core. Starch is gelatinized during the manufacturing process. Due to its hydrophilic nature, it functions by controlling the rate of water loss during drying of the board. Gelatinized starch migrates to the surface and controls the rate of crystallization of the gypsum, providing a strong bond between the gypsum and the liner.
In the process of making Gypsum Board, VIKAS GYP GUM is one of the necessary additives.
