A masterbatch having epoxy-functionalized silicone as a slip additive, the polypropylene compound that the silicone-containing masterbatch has been let down into, and the plastic articles and films from such compounds having improved slip properties are disclosed. The improved slip properties are evidenced by (1) essentially no migration of the slip additive 12 weeks after manufacturing, (2) a dynamic coefficient of friction value of less than 0.4 and a static coefficient of friction 0.6 or less within the first day of manufacturing according to the ASTM D1894-01 method, and (3) less than 15% change in the dynamic and static coefficient of friction values between the first day of manufacturing and 20 days after manufacturing.

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.

A completely non-halogenated flame retardant polycarbonate compound is disclosed. The compound comprises a polycarbonate, non-halogenated drip suppressant ingredients which react in the presence of heat to form a drip suppressant adduct, and a non-halogenated char former. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test.

High temperature nylon compounds that are flame retardant using non-halogenated ingredients are disclosed. Poly phenylene ether, or alternatively the combination of polyphenylene ether and bismaleimides, act as synergists with polyphosphonate to achieve a V-0 rating in a UL 94 test at thicknesses of about 3.18 mm or, preferably, about 1.59 mm.
