Notes:
Three blown-film-grade low-density-polyethylene (LDPE) resins were studied using different rheological techniques. Eccentric rotating disks (ERD), cone-plate viscometry, capillary rheometry, annular die extrusion, and non-isothermal stretching of a filament were used. The viscoelasticity of the melts was found to play a dominant role in the observed behavior. Extrudate appearance in annular flow, melt strength, and extensibility are affected by melt elasticity. A correlation was found between the maximum draw ratio of a filament stretched under non-isothermal conditions and minimum film thickness.
