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.

Wiring and Cable with Silane

Improved wiring and cables performances with Silanes
Vinylsilane crosslinking technology is well established in the manufacture of low voltage wire and cables (< 1kV) for industries such as: power distribution, telecommunications, transportation and appliances 

However, due to having superior process flexibility, enabling outstanding performance and higher extrusion rate, Silane technology is penetrating the medium voltage market.

The unique set of benefits provided by Silane technology will allow the development of new generation cables with optimized cost and performance. Despite the fact that this technology is easy to implement, the selection of the right system needs to integrate not only material performances but also processing conditions and logistic constraints.

Benefits of Silane crosslinking in cables

High heat resistance

Process flexibility
High Speed extrusion
Good electrical retention
Good abrasion resistance

In cable applications, Silanes are also used as coupling agent between Halogen free FR additives (ATH, MDH) and the polymer in order to achieve the required set of properties.
