Polyolefin compounds for cables and pipes boost your performance

Cable manufacturers world-wide rely on Dynasylan® for their product performance. By continually finding new ways to synthesize and by minimizing the production of waste material, manufacturing processes can be constantly optimized.

Silanes must be designed to be safe, nonpolluting and non-harmful not just in the end product, but also for the environment and for those involved in their production and application.

Strength, flexibility and the ability to resist external influences depend on the mechanical properties of a structure, which are the result of the cohesion of all components. Evonik Resource Efficiency offers the matching Dynasylan® product.

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

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.
