Silica Fume

• Silica Fume is a fine-grain mineral additive used in plasterboard and drywall manufacture to improve the properties of the gypsum core. The inclusion of Silica Fume serves to enhance fire protection in plasterboard and drywall products because when exposed to high temperatures, the silica fume particles can react with the gypsum to form a Calcium Silicate Hydrate (C-S-H) gel that can help to protect the gypsum core from damage and prevent the spread of flames.

  The use of Silica Fume in plasterboard and drywall manufacture not only helps to improve the fire resistance of plasterboards but also the strength, water resistance, and which can enhance their durability and safety.
