Flexible Pre-oxidized Fiber Aeroge Insulation Blanket-AG35

Pre-oxidized Fiber Aerogel-AG35

Product Description

AG35 Pre-Oxidized PAN Fiber Aerogel Sheets are high-performance thermal insulation materials produced by bonding aerogel to a pre-oxidized PAN fiber mat substrate using a sol-gel process and supercritical extraction to remove organic solvents. This process results in an ultra-thin, highly efficient insulating material that is heat-resistant, flexible, and offers excellent tensile strength.

Pre-oxidized PAN fiber is derived from polyacrylonitrile (PAN) and has a maximum long-term operating temperature of 350°C. It demonstrates excellent thermal stability in high-temperature environments. In addition, it has strong resistance to acid and alkali corrosion, making it highly durable in harsh conditions. It also serves as an excellent electrical insulator.

While pure aerogel is inherently brittle, the combination with pre-oxidized PAN fiber mat enhances the material’s structural strength. This synergy not only improves its physical durability but also maintains its superior insulating, electrical insulating, and anti-corrosion properties, making it an ideal material for demanding applications.

Product Advantages

  1. Excellent fire resistance: With a maximum long-term operating temperature of up to 350°C, the material remains stable and does not melt or drip under high temperatures, ensuring reliable performance even in extreme heat.
  2. Free from harmful substances like asbestos, safe for human health: The absence of harmful components such as asbestos makes this material a safer alternative, reducing health risks compared to conventional insulation materials.
  3. Ultra-thin thickness for space-constrained applications: Its exceptionally thin profile allows it to be used in areas with limited space, such as in 3C electronic products or battery chips, where traditional insulation materials would be too bulky.
  4. Extremely low thermal conductivity: With a thermal conductivity as low as 0.018 W/m·K at room temperature, it only requires a thickness of one-quarter to one-third compared to traditional materials to achieve the same level of insulation, offering superior thermal management in compact designs.
  5. Precise control over dimensions: The material can be precisely cut to meet the specific requirements of small electronic components, minimizing waste and allowing for exact fitment in tight spaces.
  6. High flexibility and tensile strength: With a tensile strength of up to 1 MPa, it is flexible enough to withstand mechanical stresses without breaking or cracking, making it ideal for applications that require durability and flexibility.
  7. High chemical stability: The material is resistant to most acids and alkalis, ensuring it maintains its performance even in harsh chemical environments, offering long-lasting reliability.
  8. Electrical insulation: It is an excellent electrical insulator, which is particularly important for use in electronic components and batteries, where preventing electrical conductivity is crucial.
  9. High hydrophobicity: With a water resistance rate of up to 98%, it effectively prevents corrosion caused by water ingress, protecting metal components from damage and maintaining the integrity of the insulation over time.

Manufacturer & Engineering Notes

Manufacturing & Project Experience

Anchor Aerogel produces AG35 by bonding aerogel to pre-oxidized PAN fiber mat through sol-gel processing and supercritical extraction, yielding ultra-thin sheets for thermal and fire barriers. Our work with electronics, battery, and protective-equipment customers is drawing-driven: we supply standard 1480 mm wide sheets as well as precisely cut parts matched to component geometry, with samples available for qualification and safety testing. Published values on this page reflect our standard product; cutting tolerances, packaging formats, and any additional test data are confirmed in the current TDS or part specification before production supply.

Engineering Boundaries & Custom Options

Standard AG35 covers 0.5-4 mm thicknesses at 1480 mm width and 220 kg/m3 density, with customized thickness and precise die-cutting available. Performance is bounded by the 350°C long-term temperature limit of the PAN-based fiber and a -50°C lower bound; conductivity at 25°C is 0.018-0.023 W/(m·K). The material is electrically insulating, asbestos-free, 98% water resistant, and resistant to most acids and alkalis. Limitations: it is not structural, not rated above 350°C, and safety-critical uses such as battery thermal barriers require validation in the customer's own assembly testing.

Frequently Asked Questions about Pre-oxidized Fiber Aerogel Blanket (AG35)

Technical answers for overseas buyers, engineers, and project specifiers. For project-critical values, request the current TDS before final design.

AG35 is an ultra-thin insulation for space-constrained and fire-sensitive duties: 3C electronics (computers, communication, consumer electronics), fire protection suits, welding fire blankets, automotive battery chip fire insulation, thermal insulation for electronic components, insulation and cold insulation for small pipelines, fire protection for circuit boards, and thermal insulation for small containers. With thicknesses from 0.5 mm and thermal conductivity as low as 0.018 W/(m·K), it provides thermal barriers where traditional insulation would be too bulky. Send component drawings with your inquiry for precise-cut parts.

AG35 bonds aerogel to a pre-oxidized PAN fiber mat substrate using a sol-gel process with supercritical extraction to remove organic solvents. Pre-oxidized PAN fiber, derived from polyacrylonitrile, has a maximum long-term operating temperature of 350°C with excellent thermal stability, and the applicable temperature range is published as -50 to 350°C. The material remains stable at high temperature and does not melt or drip. The fiber reinforcement overcomes the inherent brittleness of pure aerogel, giving the sheet flexibility and tensile strength up to 1 MPa.

Standard thicknesses are 0.5 mm, 1 mm, 2 mm, 3 mm, and 4 mm, with customized thicknesses available, and the standard width is 1480 mm. Density is published at 220 kg/m3. The material can be precisely cut to the specific dimensions of small electronic components, minimizing waste and enabling exact fitment in tight assemblies. Dimensional tolerances are not listed on this page, so where parts must meet tight assembly tolerances, confirm the achievable cutting tolerance and sheet flatness in the current TDS or on the part drawing before production ordering.

AG35 contains no asbestos or similar harmful substances, making it a safer alternative to conventional insulation for personnel and assembly environments. It is an excellent electrical insulator, which is critical around electronic components, circuit boards, and battery cells where preventing electrical conduction matters. Its water resistance rate of up to 98% helps prevent water-ingress corrosion of metal parts, and its chemical stability resists most acids and alkalis. For battery thermal runaway barriers or other safety-critical uses, validate the material in your own cell or pack testing before design freeze.

AG35’s ceiling is the 350°C maximum long-term operating temperature of the pre-oxidized PAN fiber; above this, a glass or ceramic fiber based aerogel product should be evaluated. Thermal conductivity at 25°C is 0.018-0.023 W/(m·K), and at these thin gauges the material provides roughly one-quarter to one-third the thickness of traditional materials for equivalent insulation. The sheet is flexible with high tensile strength but is not a structural component, and cut edges should be produced with sharp tooling. Confirm performance under your actual thermal, electrical, and chemical exposure conditions before specification.
