在聚乙烯树脂挤出过程中，在一定温度范围内确定了选定的挥发性有机物和颗粒物排放的排放因子。使用中试规模的挤出机。低密度聚乙烯 (LDPE) 的聚合物熔融温度范围为 500 °F 至 600 °F，线性低密度聚乙烯 (LLDPE) 的聚合物熔融温度范围为 355 °F 至 500 °F，高密度聚乙烯 (HOPE) 的聚合物熔融温度范围为 380 °F 至 430 °F。计算每种测量物质的排放因子，并报告为每百万磅加工的聚合物释放到大气中的磅数（ppm[wt/wt]）。根据产量，加工商可以使用这些排放因子来估算与本研究中使用的条件类似的聚乙烯挤出操作的排放量。
Emission factors for selected volatile organic and particulate emissions were developed over a range of temperatures during extrusion of polyethylene resins. A pilot scale extruder was used. Polymer melt temperatures ranged from 500 °F to 600 °F for low density polyethylene (LDPE), 355 °F to 500 °F for linear low density polyethylene (LLDPE), and 380 °F to 430 °F for high density polyethylene (HOPE). An emission factor was calculated for each substance measured and reported as pounds released to the atmosphere per million pounds of polymer processed (ppm[wt/wt]). Based on production volumes, these emission factors can be used by processors to estimate emissions from polyethylene extrusion operations that are similar to the conditions used in this study.
