AGF-AP Ultra-Thin PET Aerogel Insulation Film

AGF-AP combines an ultra-thin 1.9 μm PET substrate with a nano-dispersed aerogel coating. The aerogel layer forms a continuous, dense thermal barrier with a smooth, soft surface that is dust-free and odorless. Standard thicknesses are 100±10, 200±20, and 300±20 μm, with a customizable range of 70-300 μm, giving designers a thin insulation option for space-constrained stack-ups. The aerogel layer’s thermal conductivity is 0.022-0.026 W/(m·K), well below conventional polymer or foam insulators of similar thickness, so meaningful thermal resistance can be added without consuming the limited gap available inside compact devices.

AGF-AP targets precise thermal management in sensitive electronics: smartphones, smartwatches, tablets, LED backlights, TVs, and battery modules are named by the manufacturer, together with wearable devices, laptops, OLED displays, smart TVs, digital cameras, and broader consumer electronics. It blocks heat transfer in confined spaces while also providing electrical insulation between heat sources and adjacent parts. Its combination of thinness, cuttability, and PET-reinforced tear resistance makes it especially suitable for wearable devices, foldable phones, and other flexible electronics where insulation must follow curved surfaces without cracking or adding measurable bulk to the assembly.

Per the published specification table, AGF-AP has a temperature resistance range of -40 to 130°C and a continuous operating temperature of -20 to 120°C. Dielectric strength is rated at ≥4 kV/mm and volume resistivity at ≥1.0×10¹³ Ω·cm, so the film contributes both thermal and electrical insulation in one thin layer. These figures are typical published values rather than lot-guaranteed minimums; where insulation performance is safety-relevant, confirm the current TDS and validate on the final stack-up. No UL94 flame rating is published for this model, so any formal flammability requirement should be discussed with the factory during technical review.

Yes. AGF-AP is supplied in rolls with customizable size, and thickness can be tailored between 70 and 300 μm in addition to the three standard gauges. The film is described as easy to cut and fit, and the PET substrate adds toughness for converting, so it is well suited to die-cut parts, strips, and sheets matched to component outlines. Buyers can share drawings or CAD files so the factory can confirm achievable tolerances and propose roll widths or pre-cut formats that drop directly into the assembly process. Evaluation samples can be arranged ahead of production commitments.

AGF-AP is not self-adhesive; it is positioned within the assembly and fixed by the designer’s chosen method after removal of any protective liner. Cut the film to shape, place it against the heat source or sensitive component, and secure it with the enclosure, adhesive tape, or other means appropriate to your stack-up. Store rolls in a dry, room-temperature environment; the published shelf life is three years. The PET substrate gives the film moisture and aging resistance for long-term stability, but keeping rolls sealed and clean until use preserves the dust-free aerogel surface required for sealed electronic devices.
