Process details of BP Chimie's LLDPE

摘要: There are several different Linear Low Density Polyethylene processes. All developments from former HDPE and LDPE Basically there three kinds of LP processes: Solution process developed by Du Pont, DSM some others Slurry Phillips its licensees, Hoechst, Montedison Fluidized bed BP Chimie UCC Due to the characteristics each process, adaptation LLDPE resin may have limitations: Limitations product range due poor solubility higher molecular weight (or lower Melt Index) polymers in solution solvent. Polymer viscosities become too high. low density production slurry using a diluent: swelling polymer viscosity increase with degree branching polymer. This results rate limitations densities.
