Do You Know The Difference Between Silicone Wire And Rubber Wire?

Published by Author: Joey Wan September 05,2022

Silicone wire and rubber wire can easily be mistaken for the same type of wire, but there are significant differences in performance and material between the two.

Silicone wire, the industrial name is AGR silicone rubber wire, is a wire made of silicone material, suitable for temperature range -60°-200°, voltage 300/500V, conductor material is tinned copper wire, insulator is silicone rubber, braid is Fiberglass + Silicone. Let me introduce to you "the difference between silicone wire and rubber wire and the advantages and disadvantages of silicone wire".

Rubber is divided into natural rubber and synthetic rubber. Natural rubber is a high polymer of isoprene, and synthetic rubbers generally include cis-butadiene rubber, neoprene, styrene-butadiene rubber, etc. After cross-linking treatment, the rubber can recover quickly under the action of external force, and has excellent physical properties and chemical stability.

Silicone wire has good high and low temperature performance, good insulation performance, high-quality organic chemical stability, high pressure resistance, aging resistance, long service life, softness, and is conducive to installation.


The molecular chains of rubber can be cross-linked. When the cross-linked rubber is deformed under the action of external force, it has the ability to recover quickly, and has good physical and mechanical properties and chemical stability.

Simply put, the heat resistance of silicone rubber is not only related to the type of raw rubber, vinyl content (crosslinking density), the type of heat-resistant additives and fillers in silicone rubber, and the amount of silicone rubber, but also the pH value of its rubber compound. related to moisture content. There are also some problems with the application of silicone rubber cables because it is very expensive. This is not conducive to its popular use, because the investment cost is relatively large, so the initial investment is also large.


After the cable is laid, it will be energized for a long time. Electricity will generate heat energy, the allowable working temperature of the conductor is 70°C, and the allowable long-term working temperature of the silicone wire is 180°C.
