Effect of particle size on the flame retardancy of poly(butylene succinate)/Mg(OH)(2) composites

摘要

Poly(butylene succinate)/magnesium hydroxide (PBS/Mg(OH)(2)) composites were prepared by melt compounding to investigate the effect of particle size on the flame retardancy of PBS. Their flammability properties were investigated by limiting oxygen index, UL-94, and cone calorimeter tests, which suggested that the medium-sized Mg(OH)(2)-5 mu m displayed the best flame retardancy. The residual char structure were analyzed and indicated that Mg(OH)(2)-5 mu m could form a better protective layer than other sized particles, leading to the better flame retardancy to PBS.
