Dynasylan® for the wire & cable and pipe industry

Cable manufacturers world-wide rely on Dynasylan^® for their product performance.

Dynasylan^® enhances the properties of compounds significantly:

• Increase in the thermal dimensional stability of polyethylene which results in adequate strength at elevated temperatures,
• High filler-loading levels in halogen-free flame retardant (HFFR) compounds with good melt processability and improved physical properties,
• Superior wet electrical properties in white-filled rubber.

For wire & cable moisture-cured XLPE and mineral filled polyolefins or rubbers are used. For these applications as well as for moisture-cured PEX-b pipes silanes are needed as

• Adhesion promoters and coupling agent for highly filled compounds,
• Grafting & crosslinking additives for grafted polyethylene (PEg) resulting in PEX pipes or XLPE cables.

Dynasylan^® for crosslinking

Vinylsilanes are used for grafting onto a polyethylene (PE) chain. This grafted PE (PEg) will be crosslinked in the presence of moisture and a catalyst to form XLPE and PEX compounds for the wire & cable and pipe industry.

Another approach is the use of vinylsilanes as a functional co-monomer in a co-polymerisation process together with ethylene and other olefins.
