Polymer pilot center

Sulzer maintains a world-class, fully equipped polymer pilot center for process development and customer testing in Winterthur, Switzerland. The pilot facilities are ideal for performing all kinds of testing ranging from bench-scale mixing experiments through to complete polymerization processes.

On six floors, our experienced team of pilot technicians, R&D engineers and modeling specialists build your customized pilot plant for proof-of-principle testing and collection of scale-up data. We also operate fixed scale-down pilot plants of our EPS and PLA technology for customer demonstration and sample production.

Capacity of the pilot plants

The scale of our pilot plants is usually set to production capacities between 5 and 50 kg/h. Within our PLA technology portfolio, Sulzer will soon be operating its own 1 000 t/a demonstration plant for production of larger samples and scale-up tests. This demonstration plant will be on-stream as of early 2012.
