The miscibility of fire retardants and nylon can be divided into two categories: one is melting at the operating temperature and the other is dispersed as particles in the polymer matrix. For the former, due to the difference in melt viscosity and crystallinity, it is processed and molded. During the process, the surface properties and mechanical properties of the material may be deteriorated: the latter is related to the group, particle size, and uniformity of dispersion of the particulate additive. In some cases, polymeric flame retardants can The mechanical properties reach the level of non-flame retardant systems. Because the bonding properties of melamine cyanurate are similar to nylon, it has good compatibility with nylon, and its fire retardant nylon has no precipitation and blooming.
