Because the high arc resistance value of nylon is greatly affected by fire retardants, the arc resistance index may be the most important.① Performance, due to the presence of moisture and other pollutants, melamine cyanurate fire retardant nylon has surface degradation under the action of the surface electric field, and the arc resistance A conductive path may be further formed. When current flows through its surface, it can cause permanent damage, leading to eventual component failure.
As far as the application in the field of electronics is concerned, the differences in volume resistivity (IEC-C33), dielectric constant (IEC2500) and dissipation factor (IEC250) of different flame retardant systems are not significant.
