Active Building
Film®

GRAPHENATON Technologies SA is a Swiss OEM manufacturer specializing in the industrial printing of innovative graphene-based inks onto functional films. Our ABF® (Active Building Film®) technology platform is a globally unique infrared heating solution that is commercially mature and ready for integration.

We design, develop, and manufacture our films in-house, then supply them to manufacturers who incorporate them into their products. Our target markets include construction (under flooring, walls, ceilings, ultra-thin radiators), mobility (automotive, rail, aerospace, marine, EV batteries), and industrial equipment. Each project is tailored by our R&D team to meet the client’s technical and commercial requirements.

Le film ABF® est constitué d'une fine couche d'encre graphène imprimée à basse température (< 120 °C) sur un substrat flexible — polymère, tissu, verre, plaque de plâtre ou composite. Des électrodes en argent ou en cuivre déposées sur les bords assurent une distribution uniforme du courant.

When powered, the film converts electrical energy into heat through the Joule effect, with an efficiency close to 100%. The heat is emitted in the infrared spectrum (8 to 14 μm) and is absorbed directly by people and solid surfaces, without first having to heat the air.

Conventional heating systems (convector heaters, radiators, hydronic floor heating) first heat the ambient air through convection, which creates a temperature gradient (warm air at the top, cool air at the bottom) and results in significant energy losses due to air movement. In addition, hydronic systems or those with high thermal mass experience significant startup inertia.

ABF® operates using infrared radiation: heat is transmitted directly to solid objects, felt as soon as the unit is turned on, and distributed evenly without unnecessarily heating the surrounding air. The result: the room warms up in less than 3 minutes, compared to 1 to 3 hours for a hydronic heating system, and energy savings of 30 to 40%.

Thanks to its thickness of less than 1 mm and its flexibility, ABF® film can be integrated into almost any existing substrate without requiring major modifications to the substrate.

In buildings: under hardwood floors, in walls, on ceilings, integrated into drywall or glass. In transportation: cars, trains, airplanes, boats, as well as thermal management for electric vehicle batteries. In appliances: heated furniture, ultra-thin radiators, home appliances, and industrial applications. Its range of applications is universal.

Yes, and these savings have been confirmed by independent tests: 40% less energy consumption in buildings compared to conventional heating, and 35% less in transportation compared to onboard heating systems. In a test where the temperature was raised from 18°C to 23°C, a radiator equipped with ABF® consumed 8.3 times less electricity than a standard 500-watt convector heater.

These savings are based on three key factors: nearly 100% electrical conversion efficiency,the complete absence of thermal inertia (no losses during startup or shutdown), andthe efficiency of infrared radiation, which directly heats people and surfaces without wasting energy in the air.

ABF® is the only heating film in the world capable of delivering 5 kW/m² of power while being compatible with both low voltage (12 V) and standard voltage (230 V), up to 400 V AC. No other heating film on the market combines these two features.

Because the resistivity of the graphene layer can be precisely controlled during printing, the power density can be customized to suit the specific application: from low power density for a heated wall to high power density for industrial or automotive applications.

Yes. Infrared radiation (8 to 14 μm) corresponds exactly to the wavelength of the natural thermal radiation emitted by the human body—a completely safe form of radiation that has been used for decades in balneotherapy and medicine.

Unlike convection heating systems, ABF® does not dry out the air, does not stir up dust or allergens, and produces no noise. Its construction using graphene—a pure carbon material—avoids the use of critical rare metals and facilitates recycling at the end of its life.

GRAPHENATON Technologies SA operates as an OEM platform: we supply the heating film, and you integrate it into your products. Each project is developed in collaboration with our R&D team to meet your technical and commercial requirements.

The typical process consists of four phases: 1. Specifications — electrical, mechanical, and environmental design. 2. Prototyping — provision of qualification samples. 3. Industrialization — quality validation and ramp-up. 4. Mass production — delivery according to your volume requirements and deadlines.

The ABF® film contains no moving parts, no heat transfer fluid, and no hydraulic circuits —and therefore no components subject to mechanical wear. The graphene layer, encapsulated in a protective coating tailored to the application (waterproofing, mechanical strength, electrical insulation), is chemically very stable.

Under normal conditions of use, the expected service life is equivalent to that of the substrate into which the film is integrated—typically several decades when used in building construction.

Yes. GRAPHENATON Technologies SA provides a 10-year warranty for the ABF® film, subject to the conditions of use specified in the project specifications. This warranty covers the film’s continued electrical and thermal performance—resistivity, power density, and uniformity—for the entire duration of the warranty period.

This lifespan reflects graphene’s chemical stability and the complete absence of wear parts in the film’s design. The specific warranty terms (scope, exclusions, implementation) are agreed upon on a case-by-case basis with each OEM customer, in line with their specific application sector and their own downstream commitments.

The IP rating (IEC 60529 standard) indicates the resistance of electrical equipment to two types of external hazards. The first digit indicates protection against solid objects and dust (from 0 to 6, with 6 being completely dust-tight). The second digit indicates protection against liquids (from 0 to 8, with 8 corresponding to prolonged immersion).

ABF® film is inherently IP5x-rated: it is resistant to solid objects larger than 1 mm. As for the second digit, the connectors and packaging determine the final level of water resistance—they are selected on a case-by-case basis depending on the intended application.

GRAPHENATON Technologies SA works with its customers to design custom configurations up to IP68 (fully waterproof, suitable for continuous immersion), particularly for demanding industrial, marine, or outdoor applications.

Yes. ABF®’s performance—conversion efficiency, thermal uniformity, and energy savings of 30 to 40 percent—has been measured and validated through independent testing, including comparative case studies of radiator heating cores.

The applicable certifications depend on the integration sector (building, automotive, rail, and aerospace standards) and are supported by our R&D team throughout the integration process.

Yes—in very concrete terms. ABF® aligns with the CSRD by reducing the carbon footprint of buildings and mobile products in several key areas:

Energy savings of 30 to 40% during operation; no thermal inertia, thus no energy waste; no heat transfer fluids or critical rare metals; a service life matching that of the host substrate; and simplified recyclability thanks to a carbon-based composition.
