Abstract
Significant disadvantages of the use of polylactic acid (PLA), lack of good heat stability and flame retardance, have been overcome by the use of an aryl phosphate in combination with talc. The compound achieves a threshold of 65° C. in heat deflection temperature and V-0 flame retardance at 1.6 mm thickness.
