【Abstract】 At the present time, the flame retardant systems for polyamides(PA) and high temperature polyamides(HTPA) are required to impart high thermal stability and good flowability to the flame-retarded materials in order to produce small and thin-wall parts with high productivity. Three flame retardant systems, polymeric or oligomeric brominated flame retardants, non-halogen flame retardants and nanoinorganic fillers(nanoclay and carbon nanotube), for PA and HTPA were reviewed. Most of the flame retardants described in this paper were developed in recent years were described. Their performances and characteristics were summarized , and their producers and trade marks were introduced.更多还原
