Silicone wire is ubiquitous daily and has great advantages in industrial applications. In this article, we will introduce the definition, construction, and specifications of silicone wire in detail from many aspects, and we hope you will gain something from it.

What is silicone wire?

Silicone wire, an industrial name AGR silicone rubber wire, is a wire processed with silicone material, the suitable temperature range is -60℃-200℃, voltage 300/500V, conductor material is tinned copper, the insulator is silicone rubber, a braided layer is a glass fiber and silicone resin. The color of silicone wire is generally white, red, black, blue, green, yellow, translucent, etc. It is widely used in lighting fixtures, household appliances, electric heating appliances, instruments and apparatus, motor lead wires and electronics, lamps, solar panels, and other high-temperature wire environments.

What is the construction of silicone wire？

Silicone wire consists of a silicone insulation layer and tinned copper conductor. The silicone rubber sheath is soft and flexible, adaptable to temperatures between -60 degrees and 200 degrees, has stable performance, a high voltage resistance factor, the conductor consists of 7 or more oxygen-free copper wire, conductor cross-sectional area from 0.05 square to 10 square, you can choose different conductor cross-sectional area according to different wire gauge.

What is the specification of silicone wire？

Silicone wire specifications vary depending on the series, such as the size and composition of the conductor, the size of the insulation thickness, the size of the wire diameter, the level of voltage resistance, etc. According to the UL standard, the common silicone wire models in our daily life are 3239, 3135, 3132, 3123, and 3512, in addition to the market demand, also derived from the extra soft silicone wire.

Among them, 3239 silicone wire is stronger than other models in terms of voltage resistance, with 3KV, 6KV, 10KV, 20KV, 30KV, and 50KV different voltage levels; while other products are generally between 300V-600V voltage levels. The temperature resistance is generally between -60℃ – +200℃.

As one of the important members of the high-temperature wires, silicone wire specifications have certain rules, such as the conductor structure, to DelightFire wire 3239, 3135, 3132 three models of 22 silicone wire as an example, their conductors are used 22 0.14 tinned copper wire, conductor stranded outside diameter of 0.76, the difference lies in the use of different properties of silicone rubber as the outer insulation, insulation The thickness of the outer shell also varies (respectively: 0.5mm (3KV), 0.78mm, 0.38mm).

High temperature resistant soft silicone wire is a more special silicone rubber wire, it is different than other electrical wires are generally used in the conductor 0.05mm, 0.06mm, 0.08mm ultra-fine tinned copper wire, making the wire itself more flexible, more temperature resistance, but it is not within the scope of UL certification.

What are the advantages of silicone wire?

Silicone wire with high rated temperature, basically up to 150℃~300℃, stable electrical performance in cable high-temperature environment, good aging resistance, long service life, suitable for driving vehicles, trolleys, transmission machinery and other mobile equipment with special requirements such as resistance to pulling, heat resistance, corrosion resistance.

Ultra-high temperature heat-resistant silicone wire with corrosion and waterproof characteristics, stable electrical performance, outstanding aging resistance, and longer service life in high-temperature environments. The electrical insulation performance of silicone wire: Silicone rubber has high resistivity, and its resistance can remain stable over a wide temperature range and frequency range.

Silicone wire is resistant to high temperature, cold, and abrasion, making it available for AC transmission lines and electrical control, lighting, and communication lines below 1kv. It can also be used in high-tech industrial products such as household appliances, heating equipment, drinking and blowing equipment, air conditioning equipment, lighting equipment, electronic equipment, electric heating products, computer communications, aerospace, automobiles, etc.

Silicone wire is also used in power plants, factory buildings, and chemical plant mobile equipment to exchange wire connections of less than 1kv and to control lighting communication circuits of mechanical equipment that require tensile, heat, corrosion, and other requirements.

What are the disadvantages of silicone wire?

Silicone wire is usually more expensive than PVC wire. In recent years, the price gap has become more comprehensive due to the worldwide shortage of silicone. Silicone wires are less abrasion resistant by nature and are more likely to be punctured or cut if there is sharp or pointed metal in the environment they are used in compared to PVC wires, so fixed laying is more recommended for use. The nature of silicone produces static electricity, so they tend to attract dust and grit, making it more difficult to keep clean and detect defects or cable damage.

Why can silicone wire withstand high temperatures?

Silicone wires are mainly composed of alternating silicon and oxygen atoms.

Standard silicone is mainly composed of silicone chains containing methyl and a small amount of vinyl. The introduction of phenyl can improve silicone’s high-temperature and low-temperature resistance, and the performance of vulcanized silicone is greatly improved. It is suitable for the high-temperature range below rated voltage 600-30KV; it has excellent high and low-temperature resistance, flame retardant, radiation resistance, aging resistance, ozone resistance, water resistance, etc. They are widely used in lighting, super heavy, transportation, machinery, electrical, medical and health, metallurgy, aerospace, new energy, lithium battery, power generation system, and other high-temperature industries. As transmission lines of electrical equipment, control, monitoring lines, power connection lines of various mobile power devices, control signal transmission, etc.

What is the standard definition of high-temperature resistant wire?

We can call the wire and cable rated at 125°C and above a high-temperature resistant wire. Wire and cable can be a single conductor or multi-conductor. This product is generally a conductor (ultra-fine bare copper or tinned copper or nickel-plated copper, etc.) and insulation layer (modified PVC, silicone, FEP, etc.) or sheath layer (glass fiber braid or K-fiber material).

The two key factors that make high-temperature resistant wire suitable for an application are the temperature rating of the wire and the load capacity. The temperature rating can be defined as the continuous temperature the wire can withstand during its service life. If the cable’s temperature rating is not appropriate for the environment and ambient temperature, the expected life of the cable may be affected.

In general, the high-temperature resistant wire needs to meet the UL758 standard. The high-temperature resistant wire is commonly used in silicone, Teflon, etc. Silicone high-temperature wire is used in electric heating apparatus, paint booths, lighting equipment lighting and home products, and lithium batteries. And Teflon high-temperature wire is used in instrumentation, aerospace, power smelting and chemical industry, ships, vehicles, food machinery, household appliances, baking room, and so on.

What are the differences between silicone and PVC rubber?

Different in material

PVC materials include common and environment-friendly materials, also known as ATBC-PVC, while silica gel can be certified by ROHS, which is environmentally friendly.

Different in the process

PVC products are made of polyvinyl chloride and oil together with color paste, and its raw materials are made by heating and cooling microinjection epoxy process. But the silica gel only needs to use to add the color masterbatch to suppress and deploy in the mixing machine, then put in the mold by the heating and cooling to take shape.

Different in character

Silicone products are more cold-resistant and heat-resistant than PVC products. Tableware made of silicone can be heated in a microwave, while PVC can’t.

Different outside

From the appearance, PVC products are rougher than silicone products, and silicone products have a smooth and shiny surface.

Different in touching

According to the hand feeling, the silicone product is soft with good toughness and elasticity, while the PVC soft rubber is relatively less hard. The softness and hardness can be adjusted, but the PVC does not have tenacity.

Different in burning

Silica gel products are generally transparent, with a small burning smell and powder, while PVC products will turn black after burning and smell bad when burning.

Different in the price

The raw material price of PVC products is low, made of synthetic materials, and silica gel is more expensive than PVC products in production and manufacturing.

What are the differences between silicone wire and rubber wire?

Silicone wire uses silicone rubber as an insulating material. Silicone rubber is a one-component, room temperature vulcanized liquid rubber. Once exposed to air, the silane monomers undergo condensation, forming a network structure. The system is cross-linked, cannot be melted or dissolved, has elasticity, and becomes rubbery while bonding objects. Its thermal conductivity is slightly higher than normal rubber, and it is difficult to separate the bonded objects once cured.

The rubber electric wire’s insulation material is rubber, a highly elastic polymer compound, including unvulcanized and vulcanized varieties. It can be divided into two categories: natural rubber and synthetic rubber. Natural rubber is made from the latex obtained from rubber plants by processing. Synthetic rubber is made from monomers by polymerization or condensation.

Unvulcanized rubber is generally known as raw rubber or raw rubber. Rubber that has been vulcanized is called vulcanized rubber, commonly known as cooked rubber or rubber, which is widely used in the manufacture of tires, hoses, tapes, insulating materials, rubber shoes, and other rubber products.

Rubber wire is flexible, sun-resistant, waterproof, oil-resistant, temperature-resistant (90 degrees), cold-resistant (-40 degrees), anti-ultraviolet (UV), anti-aging, and flame retardant. Life expectancy is generally at least ten years to eight years. Suitable for outdoor lighting and heat generation, slightly larger home appliances use. The skin is relatively rough, not smooth, such as frosted leather. The main feature of silicone wire is high-temperature resistance, up to about 180 degrees, low-temperature resistance to about -65 degrees, and smooth skin; the wire is very soft, so it is suitable for use in products with high heat generation, mostly used in the interior of products, automotive lighting, high-power lighting, medical machinery are useful.

How do we identify the quality of silicone wire?

The quality of silicone wire can be shown from the appearance of the wire and cable. The appearance of the silicone sheathed cable is required to be smooth and round, and glossy uniform, with no visually visible debris, no mechanical damage, no flattening, no deviation from the core (shall not exceed the prescribed deviation), bubble trachoma, bamboo knot shape and twist shape and obvious particles, etc.
