Product Description
Nano Insulation Boards are high-performance thermal insulation materials designed for EV battery packs, energy storage systems (ESS), and high-voltage electronic applications. Engineered with nano microporous technology, these insulation boards provide exceptional thermal resistance, flame retardancy, and thermal runaway protection in compact battery structures.
As EV and ESS systems continue moving toward higher energy density, battery safety and thermal management have become critical design priorities. Nano microporous insulation materials are increasingly adopted in battery pack passive fire protection because they can effectively delay heat transfer and suppress thermal propagation in limited installation spaces.
Thermal conductivity as low as 0.018–0.030 W/m·K, effectively blocking heat transfer between battery cells.
Available from 1mm to 10mm thickness, helping reduce battery pack size and weight while maintaining safety performance.
High temperature resistance up to 1000°C (grade dependent)
Non-combustible structure
Effective thermal runaway delay function
High dielectric strength helps prevent electrical short circuits between adjacent cells.
Good compression resistance
Stable structure under vibration and long-term pressure
Suitable for tight battery module assembly
Resistant to electrolyte exposure, humidity, and long-term thermal aging.
In lithium battery packs, thermal runaway propagation between cells is one of the most critical safety risks.
Nano insulation panel is designed to act as a cell-to-cell thermal barrier, providing:
Heat isolation between adjacent cells
Delay of thermal propagation chain reaction
Improved battery pack safety performance
Reduced risk of system-level failure
Better compliance with EV safety standards
It is especially suitable for high-energy density battery systems, where spacing is minimal but safety requirements are extremely high.
