Application
Vinyltrimethoxysilane (VTMO) has a wide range of applications, mainly including the following aspects:
Polymer Crosslinking: Vinyltrimethoxysilane is an important crosslinking agent for crosslinked polyethylene (XLPE). It is widely used in the manufacture of wire and cable insulation and sheathing materials, with advantages such as simple equipment, low investment, and easy control. Crosslinked polyethylene has excellent electrical properties, good heat resistance, and stress cracking resistance, suitable for manufacturing special-shaped fan-shaped wire cores and wires and cables in high-temperature environments.
Plastic and Rubber Processing: VTMO can be used as a coupling agent for composite materials of polymer systems such as polyethylene, polypropylene, ethylene-propylene rubber, silicone rubber, unsaturated polyester, and thermosetting resins. It can improve the wettability and adhesion of these materials with glass fibers, enhancing the mechanical strength and heat resistance of the materials. In addition, VTMO can also be used to prepare high-performance exterior wall coatings and organosilicon-modified polymers, such as silicone-acrylic exterior wall coatings and organosilicon-modified acrylic emulsions.
Glass Fiber Treatment: VTMO is used for glass fiber surface treatment in glass fiber reinforced plastics (GFRP), which can significantly improve the adhesion between resin and glass fiber, enhancing the overall performance of the material. It is also used for the surface treatment of inorganic silicate fillers, improving the binding force between the filler and the polymer.
Electronic Components: In the moisture-proof treatment of electronic component surfaces, VTMOS can effectively prevent moisture from affecting the components, improving their stability and reliability.
Other Applications: VTMO can also be used to prepare moisture-curable silane crosslinked polymers, such as silane crosslinked polyethylene (XLPE), giving thermoplastic and thermosetting resins better heat resistance, acid and alkali resistance, and mechanical strength. In addition, it can copolymerize with various monomers to produce modified polymers for special purposes.
