WebPolymers as a replacement for metal. Metals are replaced by polymers more and more often. In addition to the high chemical resistance, above-all the low density of the polymers is primarily a huge advantage with regard to saving weight. However, the rigidity of the materials must stand up to the challenges of the application. WebMar 18, 2024 · What is Polymer Crosslinking? Crosslinking is known as the bridging or interconnecting of two chemical compounds. A crosslinker is the molecule that is employed to create this connection. Crosslinkers can be utilized for all kinds of polymeric materials, and are especially suitable for hybrid resin systems.
