Flame Retardant and Mechanical Properties of a Copolymer PP/PE Containing Brominated Compounds/Antimony Trioxide Blends and Magnesium Hydroxide or Talc

摘要

The incorporation of two brominated compounds/antimony trioxide blends into a PP-PE copolymer were studied. Both borminated trimethylphenyl indane (FR 1808) and poly(pentabromobenzyl acrylate) (FR 1025) confer good Flame retardancy at 40/100 loading. A comparison was made with the incorporation of magnesium hydroxide at higher Loadings (up to 64/100) in the same copolymer. The mineral filler improves both fire resistance and stiffness of the Copolymer, nevertheless the high loading causes a dramatic decrease in impact resistance.
