Technology

The Lupotech T process is the High-Pressure Tubular Reactor Technology developped for the whole range of LDPE Products, including EVA and n-Butylacrylate modified LDPE Copolymers.

In the Lupotech T Process, Ethylene is polymerised to LDPE at temperatures above 150°C and pressures between 2000 and 3100 bar. For the Production of Copolymers, specific Comonomers such as Vinyl Acetate or Butylacrylate are used.

The overall Manufacturing Process can be divided into the following Steps/Process Units:

❏ Precompression of Ethylene
❏ Compression to Reaction conditionss
❏ Polymerisation Reaction
❏ Polymer/Gas Separation
❏ Recycling of Unreacted Gases
❏ Extrusion, Pelletizing
❏ Degassing
❏ Storage and Packaging
