Heavy metal-free and anaerobically compostable vinyl halide compositions, articles and landfill biodegradation
摘要:
Heavy metal-free compostable polymers, composites and articles anaerobically biodegrade in landfills in a relatively short time. Heavy metal-free composite polymeric articles and sheets such as indoor or outdoor signs, billboards, banners, images, protective barriers, backdrops and wall coverings have very useful service durations and yet are landfill biodegradable.
