Crosslinkers

Crosslinkers tragen zur Ausbildung eines dreidimensionalen Netzwerks bei und verbessern dadurch Materialeigenschaften wie Elastizität, Festigkeit und Wärmebeständigkeit.

Crosslinkers in the polymer industry werden eingesetzt, um die Materialeigenschaften von Polymeren zu verbessern. Vernetzer finden typischerweise Anwendung in EVA (Ethylen-Vinylacetat). Durch die Zugabe von Vernetzern während des Herstellungsprozesses von EVA können die physikalische und die mechanische Stabilität erhöht werden. Im Detail beeinflussen Vernetzer Festigkeit, Härte und Dimensionsstabilität von EVA positiv.

Crosslinkers in the rubber industry are used to form three-dimensional networks. The crosslinkers, which are usually sulfur-based, form sulfide bridges between the polymer chains of the rubber, thereby improving the mechanical properties. The degree of cross-linking affects the properties of the rubber (e.g. hardness, toughness and melting point).
