Compounding — Process Challenge

Peroxid-Vernetzung für XLPE & Kautschuk

Kabel- & Leitungs-, PE-Schaum- und EPDM/Silikonkautschuk-Verarbeiter setzen organische Peroxide zur radikalischen Vernetzung von Polyethylen und Elastomeren ein – die Alternative zur Feuchtigkeit/Silan-Route, ausgewählt nach Zersetzungstemperatur und Scorch-Sicherheit; Co-Agenten erhöhen die Vernetzungsdichte und Aushärtungseffizienz.

Typical Formulation Workflow
1
Polymer & Process Definition
Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.
2
Additive Selection
Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.
3
Compounding Trial
Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.
4
Validation & Scale-Up
Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.
