SI-LINK™ DFDA-5481 NT

Catalyst masterbatch for SI-LINK polyethylene materials

DFDA-5481 Natural is a catalyst masterbatch for faster curing. The product and such as SI-LINK™Polyethylene is used DFDA-5451 silane modified polyethylene such as Natural to catalyze the crosslinking reaction of materials. Since the catalyst masterbatch is transported separately from the silane-modified polyethylene, these components are very stable during the shelf life. Only these two components will cross-link after melt mixing.

after mixing with DFDA-5451 Natural, the DFDA-5481 Natural has excellent scorch resistance and DFDA-5481 Natural has sufficient antioxidant content. therefore, this two-component system has satisfactory processing performance and product performance stability. This two-component system is very effective for copper conduits or aluminum conduits.

The recommended usage of DFDA-5481 Natural is about 5% (weight ratio). The specific dosage level depends on the process and the processing conditions used. Please contact your Dow sales representative or technical representative for your specific application to determine the usage level.
