Transparent film heater

basic information

**Features of Transparent Film Heater** - High visibility - Uniform heating across the entire heating area - Excellent thermal responsiveness - High flexibility **Basic Specifications** The transparent heater is manufactured in a customized specification according to the customer's usage purpose and conditions. Maximum size: Approximately 300mm × 420mm (sizes larger than this require consultation) Minimum size: Requires consultation (varies depending on operating voltage and required temperature) Product thickness: Approximately 0.1 to 0.3mm (excluding terminal parts) Substrate: PET film (other materials require consultation) Heat resistance temperature: Varies depending on insulation specifications, including price. Please consult for details. - For PET cover layer (thermosetting adhesive), 120℃ - For PET cover layer (adhesive), 100℃ - For overcoat agent application, 100℃ - For PET cover layer (EVA) and pouch film (EVA), 80℃ Terminal processing methods: Lug terminal attachment, electrode exposure, etc. Others: - The heater itself does not have a self-temperature control function. Separate electric control with a temperature controller or external circuits such as thermostats and PTC thermistors is required. *If you wish to request materials for this product, please contact us through our website.*

Applications/Examples of results

It is expected to be utilized for anti-fogging, condensation prevention, freeze prevention, and snow accumulation prevention in areas where visibility is primarily required. 【Application Image】 - Prevention of condensation and fogging on glass windows - Mobility assistance and response assistance heater for LCD panels in low-temperature environments - Heaters for analytical devices in the biochemical field - Heating of cylindrical glass tubes such as test tubes - Prevention of condensation on equipment viewing windows - Anti-fogging and condensation prevention for light sensors or surveillance camera housings - Prevention of functional failures due to snow accumulation and freezing in next-generation automotive components, such as LED headlights, standard equipment for cameras and sensors through automation systems, and digitalization of door mirrors It can also be utilized in various industries beyond the above, so please feel free to contact us.

  【Layered Structure of Transparent Film Heater】 - Substrate … PET film - Transparent conductive layer … The transparent conductive layer is formed by creating a thin film of various transparent conductive materials on the substrate. The formation method varies depending on the conductive material. - Electrode (bus bar) … Conductive paste, etc., needs to be arranged horizontally at both ends of the heater. - Insulation layer … PET coverlay (laminate), PET pouch film (laminate), overcoat (printing), etc. - Terminal section … Lug terminal, etc. *The above structure is just an example. All components will be customized based on customer requirements and usage conditions, so the layered structure may vary.

• 

  The transparent film heater from Heat Lab has a high transmittance and no heating wires in the heating area, making it suitable for heating areas where visibility is required.

• 

  Unlike electric wire type heaters, this heater heats up the entire surface. Its efficiency is characterized by the ability to transfer heat evenly to the target object.

• 

  The heater itself is thin and has a small volume, allowing for very quick startup and rapid heating. The graph shows the temperature measurement data for a sample of a low-resistance type transparent heater for evaluation.
