Multi-component injection moulding of liquid silicone rubbers (LSRs) in combination with thermoplastics is becoming increasingly important in plastics processing. This is also increasing the need to combine previously incompatible materials economically. This article shows how materials available on the market can be quickly combined in an injection-moulding process using a relatively simple pretreatment method – UV irradiation. In addition, this article discusses how long the activity of the pretreatment method persists and what effect this has on the adhesive bond. Finally, it is shown how partial adhesion of LSR to polycarbonates can be achieved.
