Keltan Acetm Technology : Implemented Innovation for High Quality EPDM
In this presentation the key features and benefits of the Keltan ACE™ catalyst systems will be presented. In comparison with conventional ZN technology, the more sustainable Keltan ACE™ process reduces the amount of energy required for production. Thanks to high catalyst efficiency, the process does not require catalyst extraction. It also produces no catalyst waste. The end result is that the technology is cleaner and consumes fewer scarce resources than comparable processes.
Some examples are shown in which commercialized Keltan ACE™ EPDMs products are compared with state-of-the-art Ziegler-Natta counter grades.
As an example of our continuous search towards further improved catalyst systems, a new family of Keltan ACETM catalysts is presented featuring a cyclic amidinate ligand motif. The development of this new class of easy-to-synthesize catalyst was expedited by using high-throughput tools to identify suitable candidates for up-scaled evaluation using both batch and continuous polymerization reactor set-ups. The new catalysts showed improved capability to prepare high molecular weight EPDM combined with enhanced comonomer incorporation in comparison to established acyclic amidinate variants.
