SKZ Plastics Center works with industrial partners to work on “SiliComp” research project to research innovative, continuous compounding processes for solid silicone rubbers.

Polymer dosing system roll-ex PDSE from UTH GmbH will be used to develop the process setup in the “SiliComp” research project.

Continuous compounding processes for producing solid silicone rubbers offer superior process control, better mixing properties and generally high quality consistency. They also require lower energy and therefore contribute to CO2 savings.

However, continuous compounding processes ae rarely used industrially for solid silicone rubber due to the challenging dosing and complex process control.

In the “SiliComp” research project, SKZ develops a process configuration of which solid silicone rubber can be continuously dosed in block form and compounded using twin-screw extruders and planetary roller extruders.

For this purpose, the SKZ will first develop suitable model formulations that are adapted to the industry’s requirements. A dosing system from UTH GmbH will be used to develop the process setup.

The developed model formulations are compounded using the designed process configurations and the resulting mixtures are characterized. This is followed by ensuring transferability to industrial scale, for which ENTEX Rust & Mitschke GmbH provides its in-house technical center.

The results of the project are shared in a broad-based project support committee from all areas of the plastics and silicone industry.
