Technology for better Life

Heat generated across the whole surface

Carbon nanotubes form a conductive network inside a thin film. When current flows, the network’s resistance converts electrical energy into heat (Joule heating), spread across the surface rather than along a single wire.

• Planar warmthHeat comes from the full film area, supporting even temperature.
• Far-infrared emissionWarm surfaces radiate in the infrared range, felt as gentle, penetrating warmth.
• Low-voltage friendlySuited to battery-powered and wearable designs.

General engineering explanation.

A thin stack, each layer with a job

• Protective layerInsulates and protects the active film from moisture and wear.
• CNT heating layer & flexible electrodesEdge electrodes distribute current evenly into the carbon network.
• Flexible substrateA polymer base that lets the film bend with the product.
• Temperature feedbackAn NTC sensor reports temperature to the controller for regulation and over-temperature protection.

What we evaluate during qualification

• Heat distributionInfrared imaging checks surface uniformity and flags local hotspots.
• Electrical resistance & responseResistance is tuned to the product’s voltage and power target; warm-up depends on that configuration.
• Thickness & bending durabilityFilm thickness and bend-cycle performance vary by material build and are confirmed per specification.

FlexTherm publishes several configurations with different values. Request the data sheet and test reports for your specific build.

Shaped around your product

• Dimensions & shapesFilm cut to your outline, from compact pads to larger panels.
• Electrodes & connectorsElectrode layout, lead wires and connector type matched to your assembly.
• Control integrationNTC feedback, heat levels and protection logic aligned with your controller.
• Wearable applicationsBelts, wraps, pads and garments for heating and wellness use.
