Ultra-thin Aerogel Thermal Insulation Film

Product Overview

Aerogel film is an ultra-thin, high-performance thermal insulation material made by uniformly coating aerogel slurry onto substrates such as PET film, PI film, copper foil, or aluminum foil. Depending on application requirements, double-sided adhesive and release liner layers can be optionally added during production, resulting in a variety of structural configurations.

Structurally, different base films not only enhance the mechanical strength of the aerogel film but also provide additional functionality. For example, PET-based aerogel films offer excellent flexibility, making them ideal for bonding to curved or irregular surfaces. Copper or aluminum foil bases add electromagnetic shielding capabilities in addition to thermal insulation.

With its unique material properties, aerogel film offers outstanding thermal resistance. Thickness can be as low as 50 μm, and thermal conductivity can reach as low as 0.02 W/(m·K)—far outperforming conventional insulation materials in efficiency.

Aerogel film is particularly well-suited for applications where space is limited and heat management is critical, such as in digital devices, household appliances, and e-cigarettes. In smartphones, it helps block heat transfer from processors, improving user comfort. In appliances, it protects sensitive components from high temperatures, extending product life. In e-cigarettes, it prevents burns and enhances user safety. This lightweight and highly effective insulation solution opens up new possibilities for thermal design in modern precision electronics.

Sample Request FAQs

Quick answers about requesting and receiving free samples from Anchor-tech.

Can you provide samples?

Yes. Please share some basic information about your project with us — for example, where the material will be used and at what operating temperature. Rest assured this is only so we can help you choose the most suitable material, model, and specification. We will never disclose your project details to any third party.

Can we still request samples if we cannot disclose any project information?

No. If you are unwilling to share any information about your project, we are not obligated to support your R&D effort. Please respect the labor involved: preparing each sample requires a dedicated colleague and is quite time-consuming. Moreover, without knowing where and how you intend to use our product, we cannot even determine whether it is suitable for your application.

Are samples free, and how much can I request?

We provide 2 free samples of aerogel film, each sized 150 mm × 200 mm × T (or A4 size). If you need a larger quantity or many pieces, please let us know the reason — we are glad to support you. However, if you have never seen our sample before and only want to take a look, please do not casually request large amounts. A dedicated colleague must prepare every sample, which takes considerable effort. You may first take a look; once you confirm it is likely suitable for your project, you can request more from us.

Who pays for shipping?

Shipping costs must be borne by the customer. Please provide us with your FedEx account number and the recipient information (including name, address, phone number, postal code, etc.), and we will arrange the shipment for you.

How long does it take to prepare samples?

If the item is in stock, preparation generally takes 3–7 days. If it is out of stock and requires custom manufacturing, it takes 1–2 weeks. We will prepare your samples as quickly as possible.
