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 resorcinol bis(diphenyl 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.

Abstract: A radiopaque, optically translucent thermoplastic polyurethane compound is disclosed. The use of nano-sized particles of barium sulfate optionally in combination with a minor amount of certain dispersion aids allows the barium sulfate to be sufficiently dispersed within the thermoplastic polyurethane to retain optical translucency according to a defined Haze Determination Test. Medical devices, needing both visual spectrum observation before and during in-vivo medical use and radiopacity monitoring during in-vivo medical use, benefit from this compound. Optionally, a surface enhancer can also be used.
