美国化学理事会(ACC)已就9种常用塑料树脂和4种聚氨酯(PUR)前体的生产发布了环境概貌报告。报告涉及的树脂包括高密度、低密度和线型低密度聚乙烯;聚丙烯;聚对苯二甲酸乙二酯(PET);通用型和高抗冲聚苯乙烯;聚氯乙烯(PVC)和(丙烯腈/丁二烯/苯乙烯)共聚物(ABS)。4种PUR前体分别是
The American Chemistry Council (ACC) has released an environmental profile report on the production of nine commonly used plastic resins and four polyurethane (PUR) precursors. The reported resins include high density, low density and linear low density polyethylene; polypropylene; polyethylene terephthalate (PET); universal and high impact polystyrene; polyvinyl chloride (PVC) and (Acrylonitrile / butadiene / styrene) copolymer (ABS). The four PUR precursors are, respectively
