What Is Radiation Cross-Linking?
Definition And Process
Radiation cross-linking is a transformative process that enhances the properties of polymers by creating cross-links between their molecular chains. This process involves two competing mechanisms: cross-linking and main-chain scission. Cross-linking dominates when the formation of molecular bonds exceeds the breaking of chains. The result is a significant improvement in the mechanical, thermal, and chemical properties of the material.
The process typically occurs in specialized irradiation facilities. Materials are exposed to accelerated electrons, with parameters such as absorbed dose carefully controlled to achieve optimal results. This method is particularly effective for applications requiring enhanced durability, such as wires and cables. By modifying the molecular structure, radiation cross-linking allows the use of lower-cost polymers while maintaining high performance.
