摘要:
This invention relates to a process for improving the color stability of a polyamide resin by providing a molding composition comprising 20 to 80 weight percent of a polyamide having a melting point of from 280 DEG C to 340 DEG C; 0 to 50 weight percent of an inorganic filler; 10 to 35 weight percent of a flame retardant with 50-70 weight percent bromine, and 1 to 10 weight percent of an antimony compound, adding from 0.1 to 4 weight percent zinc borate to the molding composition. The above weight percents are based upon the total amount of polyamide, inorganic filler, flame retardant, antimony compound, and zinc borate only. Molding the molding composition to make a molded part is part of the invention.
