Dynasylan® for the wire, cable and pipe industry


For wire & cable applications, 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:

Water tap, wash basin

Dynasylan® SILFIN 50 increases the lifetime of the inhouse water piping systems considerably.

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® oligomers

Multifunctional silanes with their tailor-made oligomeric structure provide different benefits:

  • Significantly reduced alcohol release (low VOC–low volatile organic component)

  • Combination of different functionalities in one molecule like vinyl, alkyl, amino, and diamino groups

  • High flashpoint

  • Safer handling and storage, additional safety during production

  • No loss of material even at elevated compounding conditions

Dynasylan® SILFIN

With Dynasylan® SILFIN we provide a wide range of ready-to-use products for the wire & cable and pipe industry but also for other thermoplastic applications.  With these easy to dose liquid products, we offer tailor-made blends consisting of all necessary ingredients for grafting and crosslinking of polyethene resulting in PEX and XLPE.

These products contain vinyl silanes and initiators for the two-step SIOPLAS® process and additionally crosslinking catalysts plus in some cases other additives like antioxidants, metal deactivator, processing aids, etc. for the one-step process (Monosil®).

Long lifetime of drinking water pipes with Dynasylan® SILFIN 50

Silane crosslinking increases the lifetime of the inhouse water piping systems considerably – and reliably – at high continuous service temperatures. At elevated temperatures, non-crosslinked polyethylene is easily deformed.

Silane-crosslinked polyethylene high density pipes show a significant weight reduction and greater resistance to crack formation. Other crucial advantages are improved corrosion, wear, and thermal resistance as well as significantly reduced laying costs.
