What is silicone high-temperature wire?
If you have purchased wires for heaters, motors, or LED lighting fixtures, you are likely to have heard of this term.
Silicone high-temperature wire is a wire with an insulation layer made of silicone rubber material.
Conductor: Tin plated copper wire (anti-oxidation)
Insulation layer: Silicone rubber, cured by high-temperature cross-linking through vulcanized tubes
The most obvious difference? It feels very soft - like a silicone baking pad, not as hard as PVC.
Why is it resistant to high temperatures?
| Comparison | Ordinary PVC cable | Silicone high-temperature wire |
| Long term working temperature | 70℃ ~ 105℃ | -60℃ ~ 200℃ |
| Performance at minus 40 ℃ | It becomes hard and breaks when folded | Still soft, bend freely |
| High temperature aging life | Brittle after 1-2 years at high temperatures | Stable operation below 200 ℃ for more than 10 years |
Where do customers use it?
We export to over 20 countries, and the top five actual usage scenarios are:
- Kitchen appliances: ovens, rice cookers, and stoves - unable to withstand humid and hot environments with ordinary wires
- LED lighting fixtures&stage lighting: High temperature inside high-power lamp housing, silicone wire prevents short circuit
- Motor&generator leads: hot and vibrating, and the insulation layer of ordinary wires is prone to peeling off
- New energy vehicle battery pack: high flame retardant requirements and high flexibility requirements
- Aerospace&Military Industry: Severe Temperature Variations, Reliability Must Be Strong
Silicone rubber high-temperature wire is not a universal wire
There are advantages and disadvantages
Advantages:
Resistant to extreme cold and heat
Soft and easy to wire
Flame retardant, low smoke, halogen-free
Stable electrical insulation performance
Shortcomings:
Afraid of scratches: Sharp metal edges can easily cut through the insulation layer
Not resistant to oil: Do not come into contact with mineral oil or gasoline, as they may swell
Expensive: It is indeed more expensive than PVC. But a rhetorical question: How much does it cost to save per meter? Is the risk of a fire from replacing one device worth it?
Three steps to choose the right silicone wire
Step 1: Check the temperature
Long term temperature exceeding 150 ℃ → Silicone wire
Below 150 ℃ → Crosslinked PE or PVC is sufficient, there is no need to spend extra money
Step 2: Check the installation space
Small bending radius, requiring repeated bending → Choose silicone wire, the softer the better
Straight wiring and fixed installation
Step 3: Check the authentication
Export certification CE/Rohs, etc
Why did you come to us?
Material not adulterated: pure silicone raw material, no recycled rubber, no inferior agents
Complete certification: CE/REACH/RoHS can be provided
Transparent delivery time: 3-5 days for sampling, 15-30 days for bulk orders, no delay
Flexible customization: conductor specifications, colors, printing, packaging methods can be customized according to your requirements
We have seen too many cases of customers buying at a low price and experiencing insulation cracking after three months - that kind of wire has a sticky surface, a hard feel, and becomes useless when baked at high temperatures.
Choosing the right line and using the right place is the greatest respect for the safety of one's own equipment.
