In recent years, with the rapid growth in demand for renewable energy power transmission, the cable industry has placed increasingly stringent demands on material performance. IOTA-560 (glycidoxypropyltrimethoxysilane), due to its excellent interfacial activity and reactivity, has become a core additive in cable insulation and sheathing materials. It reacts with organic polymers while forming strong chemical bonds with the surfaces of inorganic fillers, significantly improving the filler's dispersion and compatibility within the system. This not only enhances the cable's mechanical strength and voltage resistance but also significantly increases its long-term stability. In particular, the use of IOTA-560 in cross-linked polyethylene (XLPE) cables has helped mitigate stress cracking and insulation failure. Industry experts indicate that future grid upgrades and the construction of renewable energy power facilities will further drive rising demand for epoxy silanes.
