With the support of Gneuss innovative SFneos Filtration System, the latest addition to its range of process-constant, continuous screen changers, Renolit is now able to reuse a significant percentage of recycled material to manufacture high quality flexible PVC films without any compromises regarding product quality or production efficiency.

Customized SFneos screen changer for Renolit.

The flexible PVC films made by Renolit are coated on to polyester and in spite of separating processes, the scrap still contains a small amount of residual polyester. This causes problems with conventional slide plate screen changers – the frequent changes due to the contamination load result in production interruptions and flow disturbances.

Gneuss SFneos screen changer is extensively customized to exactly match the twin screw extruder, with extremely short and streamlined flow paths, designed with the help of flow simulation software. It operates continuously and pressure-stable, even with high and varying contamination loads.

With SFneos, Renolit can process a high percentage of recycling containing residual polyester without production interruptions and were therefore able to significantly increase the yield and efficiency of their existing extrusion line without compromising their product quality.

On post-industrial recycling applications, the Filtration Systems from Gneuss can play a decisive role in unlocking potential, making processes more cost-efficient and contributing toward sustainability.
