Abstract
A flame-resistant polyamide molding composition comprising a thermoplastic polyamide, a particular form of magnesium hydroxide, an olefin polymer having at least one functional group, and reinforcing fibers inert to the composition. The composition can be processed at temperatures above 300.degree. C. without degradation or decomposition, can be processed to produce bodies having thin walls and high rigidity, and is of particular use in the electric and electronic fields. Moreover, the bodies possess excellent flame-retardant characteristics and form no droplets on contact with heat or an open flame. Therefore, molded parts prepared therefrom retain their functional integrity to a high degree, even in the case of fire because no corrosive gases are evolved, thereby minimizing the formation of short circuits.
