High-temperature Fiberglass Silicone Rubber Heater
Product Details
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of high-temperature fiberglass silicone rubber heater in China, also supports custom service. Welcome to wholesale high quality high-temperature fiberglass silicone rubber heater at competitive price from our factory.
The main components of high temperature fiberglass silicone rubber heater are three parts:
- Silicone Rubber Base: The heater is constructed using a fiberglass-reinforced or non-reinforced silicone rubber substrate. This material is chosen for its exceptional stability over a wide temperature range.
- Heating Element: Embedded within the silicone rubber layers is a precisely etched or wound resistance wire (typically nickel-chromium alloy like Nichrome) or etched foil element. This element efficiently converts electrical energy into heat.
- Electrical Insulation: The silicone rubber completely encapsulates the heating element, providing excellent electrical insulation, mechanical protection, and resistance to moisture and chemicals.

Advantage
Excellent High-Temperature Resistance
The primary advantage. The silicone rubber matrix remains flexible and stable at continuous high temperatures where other materials would degrade.
Rugged and Durable
Resistant to moisture, chemicals, ozone, and UV radiation. The construction makes them resistant to vibration and physical impact.

Uniform Heating
The etched foil element technology provides exceptionally even heat distribution across the entire surface, eliminating hot spots.
Superior Flexibility
Can be easily bent and shaped to conform to flat, curved, or irregular surfaces, ensuring optimal thermal contact and efficient heat transfer.

Application
Industrial Equipment:
- Plastic Processing: Heating molds for injection molding, blow molding, and hot plate welding
- Packaging Machinery: Sealing jaws for plastic packaging films.
- Food & Beverage: Warming trays, process heating, and maintaining viscosity in fluids.
- Aerospace & Defense: Avionics heating, battery warming, and component thermal management in extreme conditions.
Medical & Life Sciences:
- Diagnostic Equipment: Precise temperature control for sample incubation in analyzers and PCR machines.
- Patient Warming: Used in therapeutic devices and blankets (with appropriate safety controls).
- Laboratory Equipment: Heating plates for sample preparation.
- Semiconductor & Electronics:
- Wafer Processing: Heating stages for lithography and etching.
- 3D Printing: Heated print beds to prevent warping of materials like ABS.
Transportation:
- Battery Electric Vehicles (BEVs): Heating solutions for battery packs to maintain optimal performance in cold climates.
- Sensor Heating: Preventing condensation and ice formation on critical sensors (LiDAR, cameras).
