Metering silanes with LEWA systems has the following advantages:
Silanes are used in the following industries and products:
What is important when metering silane?
In order to meet the production requirements (reproducibility, consistency, product purity etc.) of plastic cables and plastic pipe compounds for the manufacture of cable and/or wire insulation, metering must be precise, easily adjustable, and unaffected by external influences.
The extremely precise metering is effected via a hopper into the extruder (almost pressureless in laboratory applications) or into the process zone of the extruder by an injection pipe which places silane in the melt polymer. The choice of silane type depends on polymers. Special type organosilanes open new possible applications because they are important components of paints and coatings and their adhesion to various grounds is guaranteed for years.
The speed of silane crosslinking in polyethylene of cables can be influenced by:
