Where to Buy Reliable UL3512 Silicone Wire?

Zhengfeng Jan 09,2026

UL3512 silicone wire is widely used in high-temperature environments, such as the near 200°C temperatures near steel smelting furnaces, the rapidly moving joints of industrial robots, the core components of new energy vehicle battery packs, and the core components of energy storage devices. So how do you procure reliable UL3512 high-temperature silicone wire? You'll find the answer below.

01 Extreme Performance
UL3512 silicone wire is designed specifically for extreme environments, thanks to its superior materials science and engineering design. While traditional wires degrade in performance at high temperatures, UL3512 wire remains stable over a wide temperature range of -60°C to 200°C.

This temperature range means it can withstand a variety of environmental challenges, from polar cold to industrial high temperatures.

The wire has a rated voltage of 600V, sufficient for most industrial applications. Its excellent electrical insulation properties stem from a high-purity silicone rubber insulation layer, which maintains stable dielectric strength even at high temperatures.

UL3512 silicone wire also has special requirements for conductor selection. Most specifications use tinned copper wire as the conductor material, which not only improves conductivity but also enhances corrosion resistance.

In some special applications, fiberglass braiding with a silicone resin outer layer is used to further enhance the wire's mechanical strength and high-temperature resistance.

02 Parameter Characteristics

To fully understand the technical specifications of UL3512 silicone wire, it's necessary to delve into its various parameter designs. This wire is manufactured according to the UL758 standard, which is specifically applied to electrical wiring materials.

UL3512 silicone wire offers a variety of sizes, with conductor sizes ranging from 20AWG to 12AWG, covering different current carrying requirements. For more specialized applications, some manufacturers even offer a wide range of sizes from 28AWG to 2AWG (or 50mm² to 70mm²).

03 Application Areas
The superior performance of UL 3512 silicone wire makes it widely used in various high-temperature, high-reliability applications. In the home appliance industry, it is commonly used for internal wiring in high-temperature appliances such as ovens, electric heaters, and hair dryers.

These types of wires can withstand the high temperatures generated by electrical appliances while maintaining stable electrical performance.

In the field of industrial automation, UL3512 silicone wire is widely used in the wiring of industrial robots, CNC machine tools, and automated production lines.

These applications not only require wires to withstand high temperatures but also to have excellent flexibility to accommodate the bending caused by frequent equipment movement.

In the energy sector, UL3512 silicone wire can be found in everything from traditional power generation equipment to emerging new energy vehicles. It is used for transformer leads, motor leads, and connection wires for the power batteries of new energy vehicles.

These applications have extremely high requirements for the safety and reliability of the wires.

Furthermore, UL3512 silicone wire also plays an important role in specialized fields such as medical equipment, lighting fixtures (especially stage lighting and ultraviolet germicidal lamps), and instrumentation.

Whether it's high-temperature sterilization equipment or instruments requiring precise measurements, this type of wire provides a stable and reliable electrical connection.

04Packaging and Service

Packaging: UL3512 silicone wire is typically packaged in rolls, with common lengths being 100 meters/rolls and 305 meters/roll.
