Abstract
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.
Claims9
A plant for producing an extruded silicone intermediate,
- having a mixer/extruder for mixing and subsequently extruding a silicone compound including a crosslinker additive, for producing a raw silicone extrudate,
- having a heating apparatus for crosslinking the raw silicone extrudate to produce a crosslinked silicone intermediate,
- wherein the mixer/extruder is configured in such a way that during mixing and during extrusion, a temperature of the silicone compound does not exceed 60°.
A method, comprising:
- using a co-rotating twin-screw extruder for producing a raw extrudate by mixing and subsequently extruding a silicone compound.
A process for producing a raw silicone extrudate, with steps as follows:
- providing an unmixed silicone compound, comprising at least one crosslinker additive,
- adding the unmixed silicone compound to a mixer/extruder,
- mixing the unmixed silicone compound in the mixer/extruder to produce a mixed silicone compound,
- extruding the mixed silicone compound by means of the mixer/extruder.
