TCA-MF6000 is an organically modified special layered silicate structure used as a flame retardant synergistic char-forming agent in low-smoke, halogen-free flame retardant thermoplastic materials. Its unique lamellar layered structure effectively blocks gases to achieve flame retardant synergistic effects, promotes the density and strength of char formation, suppresses dripping, and can improve the mechanical properties of thermoplastic materials.
