QFR-2509 Silicone Soft Wire is a wire independently developed by us at 3F that uses silicone rubber as the insulation layer. Its core feature is extreme temperature adaptability, with a working temperature range typically ranging from -60°C to+200°C. QFR-2509 Silicone Soft Wire can instantly withstand higher temperatures and has excellent resistance to high and low temperatures, aging, ozone, and flexibility. With its excellent electrical insulation, flame retardancy, and chemical stability, it is widely used in fields that require extremely high reliability and environmental tolerance. The main applications include: household appliances, industrial equipment, lighting equipment, automotive wiring harnesses, and aerospace and other high-temperature and harsh environments. You can choose the appropriate specifications based on the temperature, voltage, and mechanical strength requirements of the actual application.

Application
High temperature industry and manufacturing
This is the most classic application area of QFR-2509 Silicone Soft Wire. In factories such as steel, metallurgy, casting, and glass manufacturing, the ambient temperature around the equipment is extremely high, and there may be splashing of metal slag. QFR-2509 Silicone Soft Wire is used to connect industrial electric furnaces, heaters, ovens, thermocouples and other equipment, ensuring that the circuit does not harden or crack under continuous high temperature, and guaranteeing stable transmission of power and signals.
Internal wiring of household appliances
Many high-power or high-temperature household appliances have strict requirements for heat resistance and flexibility in their internal wiring. Our QFR-2509 Silicone Soft Wire is commonly used for connecting heating elements in electric irons, rice cookers, ovens, toasters, coffee makers, and hair dryers. It can closely adhere to the wiring of the heating element, withstand long-term high temperatures, ensure our safety when using these appliances, and is soft and easy to assemble internally.
Lighting equipment and occasions
In situations where high brightness and dense lighting are required, the lighting fixtures themselves generate a large amount of heat. QFR-2509 Silicone Soft Wire is widely used in LED lighting (especially high-power LED modules, floodlights), stage lighting, studio lighting, indoor and outdoor decorative light strips, factory lighting, etc. Its heat resistance can prevent wires from aging in high-temperature environments of lamps, and semi transparent or colored silicone sheaths often have both aesthetic and insulating effects.
Automotive, Aerospace, and Rail Transit
The temperature near the engine compartment and motor of modern transportation vehicles is very high, and there are oil stains and vibrations. Our QFR-2509 Silicone Soft Wire is also used in automotive (engine wiring harness, high-temperature sensor connection), new energy vehicles (internal high-temperature area connection of battery pack), aircraft (wiring of some cabin equipment), and auxiliary systems of high-speed trains, providing reliable connections that are resistant to high temperature, oil, and bending in narrow spaces.
