Silicone Rubber Heating Coil
Product Details
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of silicone rubber heating coil in China, also supports custom service. Welcome to wholesale high quality silicone rubber heating coil at competitive price from our factory.
Products Description
The core structure of a silicone rubber heating coil includes a heating layer: an inner metal resistance wire that generates heat when energized. It also includes an insulation layer: high-quality silicone rubber with excellent insulation, thermal conductivity, and flexibility. An outer protective layer: the outermost layer of silicone rubber, typically reinforced with fiberglass cloth for increased mechanical strength. Additional accessories include a temperature sensing element (thermocouple/thermistor), power leads, insulation, and a mounting device.
Products Advantages
Compared to traditional metal heating coils (such as cast aluminum and ceramic heating coils), silicone rubber heating coils offer the following significant advantages:
- Excellent flexibility and fit: They can tightly wrap around surfaces of varying diameters (custom sizes required) and irregular shapes, minimizing air gaps and resulting in extremely high heat conduction efficiency.
- Uniform heating: The heating wires are evenly distributed, ensuring uniform heat distribution and preventing localized overheating.
- Lightweight and thin: Extremely thin and lightweight, they do not add excessive load or space occupation, allowing for flexible installation.
- High temperature resistance and thermal stability: The silicone rubber substrate can operate continuously in environments ranging from -60℃ to +250℃, and can withstand even higher temperatures for short periods.
- Good insulation and safety: Silicone rubber has excellent insulation properties, high breakdown voltage, and is moisture-proof and waterproof (IP rating up to IP54 or higher), making it suitable for humid environments.
- High mechanical strength: Lined with fiberglass cloth, it is tear-resistant, abrasion-resistant, corrosion-resistant, and has a long service life.
- Energy-efficient: Due to the tight fit, heat loss is minimal, thermal response is fast, and energy-saving effects are significant.
- Easy to customize: Non-standard customization is available based on the specific size, shape, power density, voltage, and other requirements of the object being heated.
- Easy installation and maintenance: No complicated tools are required; simply wrap and secure it. Disassembly and replacement are easy.

Q&A
Q1: How do I determine the required wattage?
A: Based on target temperature, mass of object, specific heat, heat-up time, and ambient losses. Provide these details to the supplier for engineering support.
Q2: Is it waterproof or oil-resistant?
A: Standard heaters are moisture and oil-splash resistant (IP54). For full immersion, request a sealed design (IP67/IP68) with sealed leads and edges.
Q3: Can it be used outdoors or in harsh industrial environments?
A: Yes, silicone rubber is UV, ozone, and chemically resistant. For extreme conditions, additional protective covers or specific material grades are recommended.
Q4: Is a temperature controller necessary?
A: Yes, strongly recommended. Without a controller (PID + SSR/contactor), the heater will continuously overheat, risking damage or fire.
