摘　　要：概述了高压低密度聚乙烯(LDPE)的生产应用、工艺特点和对润滑油性能要求,重点阐述了超高压乙烯压缩机的润滑,要求润滑油品在极高压力下仍具有足够的流动性及减摩抗磨能力,同时,油品还必须具有热氧化安定性、材料相容性及食品安全性等方面的要求。This paper reviews the production,application,process characteristics of low density polyethylene（ LDPE） and the performance requirements on lubricants for the lubricating of hyper-compressor. Besides the requirements of therm-oxidation stability,material compatibility and food security,the lubricants for hyper-compressor must have enough flowability and anti-friction anti-wear properties under extremely high pressure.
