摘要
An arc, track and fire resistant polyamide composition comprising 30 to 74.95% of a normally flammable polyamide, from 15 to 55% of a reinforcing agent, preferably glass fibre, from 5 to 30% of a halogenated flame retardant together with a synergist for the flame retardant consisting of a mixture of 5 to 30% zinc borate and from 0.05 to 1.5% of an oxide selected from antimony, zinc, lead, ferrous, ferric, stannous, stannic and cadmium oxides or mixtures thereof, all percentages being by weight of the total weight of the composition. The compositions of the invention have a balance of electrical, mechanical and fire retardant properties not previously available in reinforced polyamide compositions.
