【Applications of Vinyltrimethoxysilane】

  Polymer Modification

Vinyltrimethoxysilane is used to modify polyethylene and other polymers by grafting its vinyl group to the polymer backbone using a radical initiator, such as peroxide. This provides a polymer with pendant trimethoxysilyl groups that may be used as moisture-activated crosslinking sites via hydrolysis of the alkoxy groups followed by condensation of the resulting silanols.

  Crosslinking of Silane-Grafted Polymers

The reaction of Silane-grafted polyethylene to form a crosslinked or vulcanized polyethylene uses water to form the crosslinks. This technology is widely used around the world for commercial applications in wire and cable insulation, tubing, and other similar uses.
 

【Benefits of Crosslinking】

  Higher maximum use temperature
  Reduced deformation under load (creep)
  Improved chemical resistance
  Superior environmental stress crack resistance
  Increased abrasion resistance
  Improved impact strength

【Advantages of Silane Crosslinking over Radiation or Peroxide Crosslinking】

  Low capital investment
  Low operating (energy) costs
  Higher productivity
  Processing versatility
  Thick, thin, or variable thicknesses possible
