LOSSBURG, Germany—Arburg GmbH + Co. K.G. featured three liquid silicone rubber demonstrations at its annual Technology Days open house. All involved two-component molding, with two LSR/LSR applications and one with LSR/polycarbonate.
As was the case for Arburg's booth at K 2016—when it molded two-color watch straps, followed by mounting of watch cases and metal buckles into the straps—the production cell was a major attraction.
The other LSR/LSR demonstration also involved two colors, in the form of two-color egg cups with the larger white component being complemented by the smaller secondary yellow core of the cup. These colors were chosen to harmonize with the egg white and yolk of a real hard-boiled egg.
The soft cups in Silopren 2670 from Momentive Performance Polymers were rigid enough to support an egg, and created a distinct impression of having similar consistency to real egg whites and yolks. In any event, LSR has more than adequate heat resistance to cope with boiled eggs.
