Q&A

Q1: What is Micro-Nano Ceramic Paper?

It is a flexible high-temperature insulation material made from special ceramic fibers and microporous nanomaterials.

Q2: What forms are available?

The product can be supplied in rolls or cut pieces, and can be laminated with PE/PET films (black/blue/white) or mica sheets for specific insulation requirements.

Q3: What is the maximum temperature resistance?

Auwin Superflex Micro-Nano Ceramic Paper is stable up to 650°C, if you need higher temperature paper, pls check another product of us: https://www.fire-insulations.com/copy-of-Ceramic-fiber-paper-Frax-1260ST-PP-p5852448.html

Q4: How does it compare to PI films?

Unlike PI films, which typically withstand ~300°C, Micro-Nano Ceramic Paper maintains integrity at much higher temperatures, Not prone to carbonization

Q5: What are the key application areas?

Primary applications include consumer electronics (smartphones, laptops, tablets, TWS charging cases, power banks) and power tool batteries. It is also suitable for medical devices, home appliances, and aerospace components.

Q6: Can it replace silicone foam in electronic devices?

Yes. It can, our ceramic paper is inorganic, durable, and more resistant to fire and mechanical stress.

Q7: How does it compare to aerogel composites?

While aerogels provide good insulation, they are often brittle and less flexible. Micro-Nano Ceramic Paper offers similar thermal performance with much higher mechanical flexibility and easier processing, also lower cost.

Q8: Is it electrically insulating?

By laminated with Mica, making it suitable for electronic devices with strict safety standards.

Q9: Does it support industry certifications?

The material can be designed to support compliance with UL94 V-0 and other fire safety standards, depending on the application.

Q10: What is the MOQ?

Samples for free, test video for free, MOQ is 500kg
