摘要:
Flame resistant and color stabilized polymer composition (P) comprising : - at least one semi- aromatic polyamide (PA); - at least one flame retardant (FR) selected from the group consisting of phosphinic salts, diphosphinic salts, polymers of these and mixtures thereof; - at least one hindered phenol stabilizer (HPS); - at least one phosphite and/or phosphonite stabilizer (PS); with the proviso that said composition is either free of stabilizer containing at least one sterically hindered amine moiety (SHAS) or comprises said stabilizer (SHAS) in an amount not higher than about 15 % by weight of the total weight of (HPS) + (PS) + (SHAS).
摘要:
Polymer composition comprising (1) at least one poly(aryletherdisulfone) [polymer (P)] of which more than 50 mole % of the recurring units are recurring units (R1): (I) wherein Ar and Q, equal or different, are divalent radicals comprising at least one aromatic ring, and (2) a combination (AC) of additives composed of at least one fibrous filler (A1), and at least one non fibrous surface modifier (A2) chosen from liquid surface modifiers and particulate surface modifiers. Shaped article comprising the polymer composition, wherein said shaped article is a sliding part suitable for being used in a friction and wear application. Method of manufacturing said shaped article which comprises solution processing, compression molding, machining and/or melt processing the polymer composition.
