Abstract: A non-halogenated flame retardant polyamide composition is disclosed which comprises a polyamide, a non-halogenated flame retardant, a PA-6 homopolymer, and at least one heat stabilizer comprising a copper-containing heat stabilizer, an amine-containing heat stabilizer, or a phenol-containing heat stabilizer. The polyamide may have a ratio of carboxylic acid to amine end groups of greater than 1.8:1. The polyamide composition may comprise less than 900 ppm of bromine. Products formed from the composition are also disclosed.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.

Abstract: A flame retardant polyamide composition comprising a synergistic combination of an epoxy-terminated brominated epoxy polymer with a tribromophenol end-capped brominated epoxy polymer. The polyamide compositions have excellent resistance to heat and good elongation-at-break properties without the presence of decabromodiphenyl ethane.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form structurally aesthetic injection-molded articles. The polyamide compositions may include from 40 wt. % to 80 wt. % of a polyamide, from 0.5 wt. % to 40 wt. % of an etchable filler, from 5 wt. % to 30 wt. % of glass fiber, optionally less than 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance and excellent mechanical properties to injection-molded articles that are substantially free of visual defects.
