Flexible nonhalogen containing thermoplastic polyolefin compositions

摘要

Nonhalogen-Containing Thermoplastic Polyolefin blends are provided which are flexible and are particularly useful in replacing polyvinyl chloride sheeting used as roofing liners. The blends comprise, in general, (1) ethylene vinyl acetate containing and (2) very low density polyethylene having a specific gravity less than 0.920, and optionally contains (3) ethylene vinyl acetate carbon monoxide terpolymer and (4) a compatibilizer blend comprising (i) a polar olefinic polymer and (ii) a non-polar olefinic polymer; all of which are chlorine free.
