In modern industry, wires and cables are indispensable basic materials, and polyethylene (PE) as the insulation and sheath material of wires and cables, its performance directly affects the service life and safety of wires and cables. Vinyl trimethoxysilane (VTMS), as a highly efficient organic silane coupling agent, plays an important role in the polyethylene cross-linking process.

1. Excellent electrical properties
Polyethylene cross-linked with vinyl trimethoxysilane has excellent electrical properties and can effectively prevent current leakage and short circuit. This is especially important for high-voltage wires and cables, ensuring the safety and stability of power transmission.

2. Good heat resistance
In high temperature environments, ordinary polyethylene is easy to soften or even melt, while polyethylene cross-linked with vinyl trimethoxysilane exhibits good heat resistance. This enables wires and cables to operate stably for a long time in high temperature environments and is suitable for various harsh industrial environments.

3. Stress cracking resistance
Wires and cables are often subjected to mechanical stress during use, and ordinary polyethylene is prone to stress cracking. The polyethylene cross-linked with vinyl trimethoxysilane has excellent stress cracking resistance, which greatly extends the service life of wires and cables.

4. Simple process and low cost
Compared with traditional peroxide cross-linking and radiation cross-linking, the cross-linking process equipment of vinyl trimethoxysilane is simple, with low investment and easy control. This greatly reduces production costs and improves production efficiency.

5. Wide range of applications
Vinyl trimethoxysilane cross-linked polyethylene is not only suitable for ordinary wires and cables, but also can be used to manufacture fan-shaped wire cores of special shapes to meet the needs of various complex application scenarios.

In short, the application of vinyl trimethoxysilane in the wire and cable industry not only improves the performance of the product, but also reduces the production cost, and has broad market prospects.
