Influence of the crosslinking speed and crosslinking type on the foam properties of waterbased high consistency silicone rubber foam
Abstract
High-consistency rubber is typically processed by extrusion. Due to its excellent properties in terms of flexibility down to low temperatures and wide operating temperature range (-50°C up to 250°C), there are a large number of applications for silicone rubber. Due to the high material costs, foaming HCR makes sense for a large number of applications, such as gaskets, dampers, insulation or similar. In this study high-consistency silicone rubber and the water-based blowing agent were mixed with different crosslinkers in a conical twin-screw mixer and then extruded in order to work out the advantages and disadvantages of different crosslinking systems. In addition to the influence of the blowing agent on the crosslinking behavior, a clear influence of the crosslinker type and quantity on the foam structure was identified.
