About AG-ST-P1200 Nano-Silica Insulation Board

Ultra-Thin High-Temperature Insulation Solution for Battery Thermal Runaway Protection


AG-ST-P1200 Nano-Silica Insulation Board is a high-efficiency thermal insulation material developed by Shenzhen Aerogel Technology using a nano-porous microstructure design. Inside the material, a large number of nano-scale pores with diameters in the tens of nanometers form an effective barrier to heat transfer.


Because these pores are much smaller than the mean free path of air molecules, heat transfer caused by gas conduction and convection is greatly reduced. At the same time, nano silica particles and reinforcing fibers interweave to form a dense internal network, further blocking thermal transmission.


As a result, the material achieves a thermal conductivity lower than still air, providing significantly better insulation performance than conventional thermal insulation materials.


With its combination of high temperature resistance, ultra-thin structure and fire protection capability, AG-ST-P1200 is designed for applications where space is limited but thermal safety requirements are extremely high, especially in battery systems and energy storage equipment.


Designed for battery safety and energy storage fire protection


As battery energy density continues to increase, managing thermal runaway propagation has become one of the most critical design challenges in battery packs and energy storage systems.


AG-ST-P1200 insulation board is developed to function as a reliable thermal barrier within these systems. It can be used in several key protection positions:


insulation layers between high-energy-density battery cells


thermal runaway barriers between battery modules


pack-level insulation layers to delay heat propagation


fireproof insulation panels for ESS energy storage cabinets



For large energy storage systems, the board can also be used as a cabinet fire insulation structure. When applied at 15–20 mm thickness, it can support A60 and A120 fire resistance designs required for many energy storage projects.


High-temperature insulation performance


AG-ST-P1200 is designed for environments where insulation materials must maintain performance under extreme heat.


The nano silica structure allows the board to maintain stable insulation efficiency even at elevated temperatures.


Key thermal characteristics include:


temperature resistance up to 1200 °C


thermal conductivity as low as 0.025 W/(m·K) at 25 °C


maintains low thermal conductivity even at 500 °C and 800 °C


stable insulation structure under high temperature exposure


These characteristics make the board suitable for battery protection structures as well as other high-temperature industrial insulation applications.


Fire protection performance for energy storage systems


Battery fires require insulation materials that not only resist high temperatures but also prevent flame propagation


AG-ST-P1200 provides strong fire safety performance:


UL94 V0 flame retardant rating


non-combustible behavior under high temperature


no toxic gas release during combustion


after 20 minutes of flame exposure at 1000–1200 °C, the back-side temperature remains below 250 °C


With sufficient thickness design, the board can support A60 and A120 fire protection structures for energy storage cabinets, helping system integrators meet fire safety requirements in global ESS projects.


Ultra-thin insulation for narrow battery structures


Modern battery systems leave very limited space for thermal protection materials. Insulation solutions must therefore provide strong thermal performance while occupying as little volume as possible.


AG-ST-P1200 insulation boards are available in 1.0–5.0 mm thickness, allowing them to be installed in extremely narrow gaps between battery cells or modules.


This thin yet efficient structure helps maintain high integration density and compact battery pack design without sacrificing safety.


Mechanical stability and electrical insulation


In battery modules and energy storage equipment, insulation materials must maintain stability during transportation, vibration and long-term operation.


AG-ST-P1200 offers balanced mechanical and electrical properties suitable for industrial environments:


good compression resistance


dimensional stability during handling and assembly


DC 3500 V electrical insulation capability


halogen-free formulation


compliant with RoHS and REACH environmental regulations


These characteristics make the board safe, stable and suitable for long-term industrial use.


Suitable for die-cutting and component integration


For battery pack manufacturers and thermal management suppliers, materials must be compatible with secondary processing and component manufacturing.


AG-ST-P1200 insulation boards are easy to process and can be converted into different structural components used inside battery systems.


This makes the material particularly suitable for die-cutting manufacturers and tier-1 / tier-2 thermal management material suppliers serving the battery and energy storage industries.

Why choose nano silica insulation board for battery safety


Battery thermal safety requires materials that combine high temperature resistance, thin structure and stable insulation performance. Traditional insulation materials often struggle to provide all three characteristics at the same time.


Nano silica insulation boards address this challenge by using a nano-scale porous structure that significantly reduces heat transfer.


For battery system designers, this brings several practical advantages.


The material can achieve strong insulation performance even in very thin layers, which is essential for modern high-energy-density battery packs where internal space is extremely limited.


The high temperature resistance allows the material to act as a thermal barrier during thermal runaway events, helping delay heat propagation between cells or modules.


The board structure makes the material easier to integrate into battery module assemblies, insulation panels and fire protection structures used in energy storage cabinets.


For manufacturers working on battery packs, ESS systems and thermal management components, nano silica insulation boards provide a balanced solution between thermal protection, structural integration and manufacturability.


Supply and customization


To support different manufacturing processes and project requirements, customized specifications are also available. Boards can be supplied in different thicknesses and can be cut into various shapes and sizes according to application needs.

Product FAQ

If you have any questions about the product, please feel free to contact our technical experts at any time via E-mail: lexie@ag-tech.cn

  • 01

    Can you produce it with a thickness less than 1.0mm?

    At present, products with thickness less than 1.0mm cannot be manufactured due to process limitations, mainly because it is impossible to ensure thickness uniformity and the basic mechanical strength of the product.

  • 02

    What are the high-temperature resistant fibers and opacifiers of the product?

    The high-temperature resistant fiber in the raw material is high-silica glass fiber, and the opacifier is silicon carbide.

  • 03

    What is the minimum gap for the edge part of packaging?

    The minimum gap can be 5mm. If it is too small, it may cause quality issues of the product after packaging.

  • 04

    What is the minimum thickness of the PET film used? Does it meet VTM-0 flame retardant requirement?

    The minimum thickness of the PET film is 0.05mm, and all films meet the VTM-0 flame retardant requirement.

  • 05

    Can the product be made softer while ensuring its performance?

    Making the nano-board softer will significantly reduce its mechanical strength and thermal insulation performance.

  • 06

    Will static electricity problems occur during the use of this product?

    The nano-board is made by powder pressing. During the transfer process, a small amount of powder will scatter into the air and generate static electricity. At the same time, the packaging film is made of PET, which is also prone to static electricity in dry air. It is necessary to add static elimination measures to the packaging equipment to avoid static electricity affecting the packaging process.
