FLAME RETARDANT HIGH TEMPERATURE POLYPHTHALAMIDES HAVING IMPROVED THERMAL STABILITY |
摘要 |
The thermal stability of flame retardant, high temperature polyamides containing an organohalogen flame-retardant such as brominated polystyrene in combination with an antimony compound such as sodium antimonate during molding and similar melt fabrication operations is markedly improved when further combined with a minor amount of calcium oxide. The thermal stability of these compositions are much improved over analogous flame retardant polyamides formulated with magnesium oxide and/or zinc oxide.
