Flame Retardant Additives

Flame retardancy aims to prevent or limit the spread of fire. There are several methods to achieve flame retardance, including:

• CFRs (Chlorinated Flame Retardants) include chlorinated paraffin. CFRs work by releasing hydrogen chloride gas when exposed to heat, which can dilute the flammable gases produced during combustion. They are commonly used in construction materials and electrical cables.
• Phosphorous-based flame retardants like TnBP (Tri-n-butyl phosphate), an organophosphate ester used as a flame retardant in plastics, coatings, and other materials. TnBP forms a char layer and releases phosphoric acid and butyl alcohol during combustion. They are commonly used in textiles, building materials, and electrical appliances.
• Fireproof blankets are made of fire-resistant materials such as fiberglass, ceramic fiber, or silica cloth. Fireproof blankets are typically used to wrap around equipment or materials to prevent ignition.
• Cementitious cement coatings and other minerals form a hard, fire-resistant layer when applied to surfaces. Cementitious coatings are commonly used for structural steel and concrete and may contain vermiculite, perlite, or gypsum additives.
