At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical role that advanced chemical additives play in shaping the future of materials science. Among these, Vinyltrimethoxysilane (VTMS), identified by its CAS number 2768-02-7, stands out as a cornerstone ingredient for enhancing polymer performance. Its unique chemical structure and reactivity make it an indispensable component in a wide array of industrial applications.

VTMS is primarily recognized for its dual functionality: a reactive vinyl group and hydrolysable trimethoxysilyl groups. This bifunctional nature allows it to act as a bridge, chemically bonding with both inorganic materials, such as glass fibers and mineral fillers, and organic polymer matrices. This bridging capability is fundamental to its function as a silane coupling agent for fiberglass adhesion, ensuring stronger interfaces and ultimately, superior mechanical properties in composite materials.

One of the most significant applications of VTMS is in the realm of polymer modification, particularly in the crosslinking of polyethylene. By grafting VTMS onto the polyethylene backbone, manufacturers can create polymers that cure upon exposure to moisture. This process, often referred to as silane crosslinking, is widely employed in the production of electrical wire and cable insulation, as well as in the manufacturing of pipes for hot water and underfloor heating systems. The resulting crosslinked polyethylene exhibits enhanced heat resistance, mechanical strength, and stress crack resistance, making it a preferred choice for demanding applications.

Furthermore, VTMS plays a crucial role in improving resin wetting with vinyltrimethoxysilane. When used to treat glass fibers and inorganic fillers, it modifies their surfaces, promoting better compatibility with polymer resins. This leads to improved dispersion of fillers, reduced melt viscosity during processing, and enhanced overall mechanical and electrical properties, especially in humid conditions. This application is vital for industries that rely on high-performance reinforced plastics.

The utility of VTMS extends to the formulation of specialty coatings. When copolymerized with acrylic monomers, it imparts desirable properties such as weather resistance and an ability to repel dust, making these coatings ideal for exterior applications. Its role as an adhesion promoter for silicone rubber to various substrates, including metals and fabrics, is also noteworthy, ensuring robust and lasting bonds in challenging environments.
