LDPE Process Chemistry & Product Training Course

Consultant/Trainer: Dr Dieter Littmann

The Petrogenium LDPE course is centred around the process chemistry of the high-pressure polymerisation of ethylene to make low density polyethylene and the associated product properties and product applications. The course provides the background to understand the specific polymer structure and how to tailor product properties by adjusting process conditions. The mean product applications for LDPE are covered and the required product properties discussed.


This Petrogenium course can be tailored for awareness/inexperienced staff, for intermediate and for experienced personnel. Furthermore the course can be customized for a specific refinery, plant or unit. The option for post-course consultancy/help-desk support is also available.

Participants may include: plant management, process engineers, laboratory personal and product developers.
