Flexible Silicone Rubber Heater (12V, 24V, 120V, 220V) with temperature control – customizable, durable, RoHS certified. Ideal for medical, industrial, aerospace, and electronics heating applications.
A Silicone Rubber Heater (also known as silicone electric heating film or silicone heating pad) is a flexible electric heating element composed of silicone rubber, high-temperature reinforced fibers, and metal heating circuits. The product is constructed from two layers of fiberglass cloth encapsulated with silicone, with a standard thickness of 1.5 mm, offering excellent flexibility and surface conformity.
The heating element uses nichrome wire or etched nichrome foil as the heat source, molded under high temperature. It can withstand temperatures up to 250°C, resist corrosion, and has high electrical insulation. Power density can reach 5.0 W/cm², supporting custom designs with integrated temperature control devices. Typical lifespan ranges from 3–5 years.
Silicone heaters are widely applied in medical devices, aerospace, battery warming, petroleum & chemical industry, and industrial equipment.

Q1: Can I customize the size, shape, and power of the silicone heater?
Yes, we offer fully customizable heaters. You can specify dimensions, thickness, voltage, wattage, and shape to fit your application.
Q2: What temperature control options are available?
You can choose from:
Q3: Can this heater be used in outdoor or humid environments?
Yes, the silicone rubber and fiberglass construction provide high resistance to moisture, humidity, oils, and mild chemicals.
Q4: How fast does the heater reach the desired temperature?
Depending on the power density and thickness, the response time can be as fast as 10 seconds to reach 100°C.
Q5: What is the expected lifespan of the silicone heater?
With proper use, our heaters typically last 3–5 years, depending on the operating temperature and environment.
Q6: Are your heaters safe for sensitive electronic devices?
Absolutely. Low-voltage options (12V/24V) and high insulation strength ensure safe operation with electronics.
