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.

Better Weatherability with Silane

Studies have demonstrated that the use of Silane crosslinking provide material with better heat aging.

Figure 1 below compares the mechanical properties retention of PEX crosslinked using different technologies at 200°C

It shows clearly that Silane PEX exhibits better retention in tensile strength than irradiation and peroxide PE
