BZFF418 is a specialized compound of carboxylate salts and silicone powder designed to significantly improve the flowability of polyamides (PA) and enhance the compatibility between polymers and glass fibers. It reduces the separation of glass fibers from the resin, thereby minimizing the appearance of exposed fibers on the surface.

BZFF418 is primarily used to improve the surface appearance of reinforced polyamides, especially in high-glass-fiber-content systems.
