Technology / Polyethylene Technology

 

ETHYDCO manufactures Polyethylene using UNIPOL™ PE gas phase process wherein ethylene and comonomer react as gases at low pressure, in presence of catalyst using fluidized bed conditions to produce granular products.

The UNIPOL™ PE Process can produce a wide range of commercial products. Whether your goal is to make high-density, medium-density or linear low-density PE, the UNIPOL™ PE Process can accommodate its wide range of densities and melt indices – with both narrow and broad molecular weight distributions, swing and Bimodal capabilities are the key to resin differentiation.

PRODIGY - Bimodal Catalyst Benefits :

  • High production rates.
  • Outstanding reactor continuity and robustness.
  • Improved resin homogeneity vs. dual reactor for power savingsduring extrusion.

The below figure illustrates an overview about UNIPOL™ PE process. The interactive animation can be shown through Univation’s website:
