Ammonium polyphosphate (APP) is a widely used flame retardant that is particularly effective in applications requiring high thermal stability and low smoke production.

Polycarbonate, a widely utilized thermoplastic polymer, is renowned for its exceptional mechanical, thermal, and optical characteristics. However, its inherent flammability poses a significant challenge, especially in industries where fire safety

Fire retardants are chemicals used to reduce the flammability of materials and slow down the spread of fire. They are commonly used in plastics, textiles, wood, and other materials to enhance their fire safety. Fire retardants can work by forming a protective barrier around the material.
