Plant for producing an extruded silicone intermediate, use of a corotating twin-screw extruder, and process for producing a raw silicone extrudate
12558831 · 2026-02-24 · ·

A plant for producing an extruded silicone intermediate has a mixer/extruder for mixing and subsequently extruding a silicone compound for producing a raw silicone extrudate. A heating apparatus of the plant serves for crosslinking the raw extrudate to give the crosslinked silicone intermediate. The result is a plant with which a silicone intermediate of this kind can be produced more economically.
