The demand for thin film heating elements have increased over the years, owing to the rise in compact-sized thermal solutions. Polyimide, a polymer of imide monomers, has excellent heat resistance, electrical properties, and tensile strength. It is used in thin film heaters as a core material, primarily because of these properties. It is lightweight, organic, and offers dimensional stability. At Therm-X, we provide thin film strip heaters in different configurations. These polyimide heaters are known for their excellent thermal efficiencies.
Features and Benefits of Thin Film Heaters
Thin Film Heaters made of polyimide are super flexible and bendable and at the same time, very durable. Therm-x has been proudly providing such Thin Film Heaters with the following features and benefits to our customers:
- Polyimide as a thin film substrate of 0.15mm in thickness can fit onto complex surfaces that may be featured with conners, edges, gaps, curves and bends. They can be fitted in small spaces or space restricted spaces.
- Installation is easy.
- Even distribution of heat across the heated surface. May be designed to enable heating of selected areas or spots with varying watt densities, different from the main area.
- Cost effective, particularly with selective heating only in required areas can further reduces the energy consumption.
- Maximum operating temperature up to 392°F (200°C).
- High watt density, up to 50 watts/in2. Rapid heat up, approaching set point within a few seconds after switching on.
- Easy visual inspection and trouble-shooting without breaking it open as the film is transparent and tenacious.
- The films inhibit fungal and bacterial growth and are known to resistant to radiation and corrosive chemicals.
- In various shapes such as pointed, long, circular etc., as determined by the contour of the surface to be heated.
Applications of Thin Film Heaters
With their flexibility, heat resistance, durability, and cost effectiveness, the Therm-x Thin Film Heaters enjoy diverse applications across industries in crucial processes. Here are some of the examples:
- Preventing dew and frost condensation for automotive cameras lenses and optical sensors.
- Anti fog of front door mirrors in automobiles.
- Deicing and anti-condensation for traffic signs or boards and advertising glow and neon signs.
- Process heating for manufacturing of silicon wafers in the semiconductor industry.
- Warming of electronic displays.
- Warming of lithium-ion battery.
- All other surface heating applications
