Transparent Heating & Color-Changing Film
A high-efficiency transparent heating film with an ultra-precision conductive thin-film coating on a transparent base film. It provides excellent visibility without obstruction while delivering stable electrical conductivity.
DEFE 150
Safe heating materials, ITO and PEDOT applied, with KC EMC certification
Fast, uniform surface heating performance delivers stable temperatures of up to 50°C
Heating by 20°C raises the insulation performance of a standard grade-2 window to grade-1 level
Combines with a smart color-changing film with adjustable transmittance for use in a variety of window environments
Film surface heating improves winter window insulation performance
- Uses transparent conductive film
- Infrared blocking function can be included
- Large-area heating of up to 2M x 2M possible
- Achieves a heat transmission coefficient of 0.25W/m²K with single-pane PVC windows
- Heating power supports both AC and DC
