Silanes as Cross-linking Agents for Polyethylenes: Techno Brief

Crosslinking is a type of polymerization reaction that branches out from the main molecular chain to form a network of chemical links and cross-linking agents are added to resins to enable this process. This Cross-linking Agents guide is designed to help you understand more about the use of silanes as cross-linking agents in polyethylenes, focusing on the benefits and main applications.

Crosslinked Pipes with Silane

Improved PE pipes performances with Silanes
PEX exhibits a unique set of properties close of themosets and silane technology enable the processing benefits and flexibility of thermoplastics. Due to its improved thermal stability under load, environmental stress crack resistance (ESCR) and resistance to slow crack growth, PEX appears as a best-in-class and cost effective material for pipe applications.

The use of PEX pipes is growing in construction and engineering markets (+12%/year) to replace metal (copper and steel) and some engineering polymers.Typical applications are:

PEX pipes with Silanes
  • Residential and commercial cold and hot water distribution systems
  • Low temperature heat transfer applications
  • Radiant floor heating
  • Snow melting
  • Hot water baseboard heating
  • Radiators

Compared to traditional plumbing materials PEX pipes demonstrate the following benefits

Performance benefits
Installation benefits
  • Electrolysis Resistance
  • Corrosion Resistance
  • Longer System Life
  • Quiet Water Flow
  • Chemical Resistance to most Chemicals

  • Faster, Easier Installation 
  • No Solvent or Chemical Joining Required
  • Lower weight

The use of silane technology provide flexible pipe facilitating installation and allowing complex shaping. When installed, pipe can be cured by the circulating hot water.
