Applications
PolymerModification
Vinyltrimethoxysilaneis used to modify polyethylene and other polymers by grafting its vinyl groupto the polymer backbone using a radical initiator, such as peroxide. Thisprovides a polymer with pendant trimethoxysilyl groups that may be used asmoisture-activated crosslinking sites via hydrolysis of the alkoxy groupsfollowed by condensation of the resulting silanols.
Crosslinking ofSilane-Grafted Polymers
The reaction ofSilane-grafted polyethylene to form a crosslinked or vulcanized polyethyleneuses water to form the crosslinks. This technology is widely used around theworld for commercial applications in wire and cable insulation, tubing, andother similar uses.
The basicreaction sequence is as follows: polyethylene is reacted (grafted) withvinyltrimethoxysilane, using a peroxide initiator, in an extruder. The graftedpolyethylene is then formed into a finished product, such as cable jacketing,wire insulation, or pipe. The forming step is usually done by a secondextrusion, during which a catalyst for the moisture-cure step is added.Finally, the formed article is exposed to moisture or hot water to causehydrolysis of the Silane and condensation to form crosslinks via Si-O-Si bondformation.
Benefits ofCrosslinking
Higher maximumuse temperature
Reduceddeformation under load (creep)
Improvedchemical resistance
Superior environmentalstress crack resistance
Increasedabrasion resistance
Improved impactstrength
Memorycharacteristics (shrink film, tubing)
Improved impactstrength
Advantages ofSilane Crosslinking over Radiation or Peroxide Crosslinking
Low capitalinvestment
Low operating(energy) costs
Higherproductivity
Processingversatility
Thick, thin, orvariable thicknesses possible
Complex shapspossible
Wilderprocessing latitude (control of premature crosslinking)
Useful withfilled composites
Applicable toall polyethylene densities and copolymers.
