Silanecrosslinking
Silane crosslinking is a process used to enhance the properties of polymers, primarily polyolefins like polyethylene. It involves incorporating silane groups into the polymer backbone, typically through a co-extrusion process with a vinyl silane monomer, such as vinyltrimethoxysilane (VTMS). This creates a polymer that is reactive towards moisture.
The crosslinking step is initiated by exposure to water, often in a hot water bath or steam.
Silane crosslinking improves a polymer's thermal stability, tensile strength, chemical resistance, and abrasion resistance. It also
