Silicone Heating Elements: Manufacturing,Characteristics And Applications


Silicone rubber heating elements  are innovative and versatile devices that play a vital role in various industries due to their flexibility, durability and efficient heat transfer capabilities. In this article, we will take an in-depth look at the manufacturing principles and basic characteristics of Silicone rubber heating elements, revealing their diverse applications in different fields.

Manufacturing principle:

The Silicone rubber heating element is a product that is composed of two layers of silicone insulation layers sandwiched between a heating conductor, combined with advanced technology and precision engineering, and can generate heat after being energized. When the silicone heater is in use, the required temperature can be adjusted according to the resistance value of the heating conductor. Compared with the PI material heater, it is thicker, but more temperature-resistant and has more buffering power. Key components involved in the manufacturing process include:

Silicone Insulation: The base material of Silicone rubber heating elements is silicone, a synthetic rubber material known for its excellent thermal stability, flexibility, and electrical insulation properties. Silicone rubber can withstand a wide temperature range and thickness, making it ideal for heating applications.

Metal heating element: It is mainly a heating conductor. Embedded in the silicone rubber matrix is a metal heating element, which is usually made of nickel-chromium alloy heating wire, copper-nickel alloy heating wire or other conductive materials. This heating element is responsible for generating heat when electric current passes through it.

Insulation layer: In order to ensure electrical safety and thermal efficiency, add an insulation layer to encapsulate the heating element. This insulation prevents direct contact between the heating element and the exterior surface, thereby minimizing the risk of electrical hazards.

Double-sided tape: Usually 3M adhesive, Crown 513 and other tapes are used, which can also be replaced according to customer requirements.

Heating element properties:

Flexibility: One of the standout features of Silicone rubber heating elements is their flexibility. This feature allows these heaters to conform to irregular surfaces, making them suitable for a wide range of applications not possible with traditional rigid heaters.

Temperature Uniformity: Silicone rubber heating elements provide even heat distribution across their surface. This ensures consistent heating, minimizing hot and cold spots, which is critical in applications where accuracy is critical.

Fast Heating and Cooling: Due to the excellent thermal conductivity of silicone rubber, these heating elements heat up and cool down quickly, providing efficient and responsive temperature control.
