Flame-retardant polyamide composition

摘要

The present invention relates to a polyamide composition comprising (amounts are based on the total composition) (A) polyamide, (B) melamine cyanurate and (C) talcum as mineral filler wherein the amount of talcum is higher than 25 wt %, and the weight ratio melamine cyanurate/talcum is higher than ⅓ and to articles made wholly or partly of this polyamide composition. The polyamide is preferably polyamide 6. The composition is commonly used in the industry of for instance electrical and electronic parts and preferably in miniature circuit breakers.
