Product Overview
The Aerogel Pad Insulation represents a cutting-edge solution for thermal management and protection of electric vehicle (EV) batteries. Often referred to as "frozen smoke," aerogel is an ultra-lightweight, highly porous material known for its superior thermal insulation capabilities. By integrating aerogel sheets into EV battery systems, manufacturers can significantly enhance battery safety, efficiency, and operational longevity. With a thermal conductivity as low as 0.023 W/m·K at 25°C, our aerogel insulation panels deliver outstanding heat resistance while maintaining a lightweight and compact profile.
Key Features
Exceptional Thermal Insulation Performance
The aerogel’s nano-microporous structure, featuring pores smaller than 100 nm, ensures minimal heat transfer between battery cells. This minimizes thermal buildup, helping to maintain consistent temperatures across the battery pack and preventing localized overheating.
Superior Fire Resistance and Safety Enhancement
Designed to withstand temperatures up to 650°C, the aerogel insulation sheets offer Class A fire resistance (UL94 V-0 certified). This critical property significantly reduces the risk of thermal runaway propagation within EV battery packs.
Lightweight and Space-Saving
With a density of just 200±20 kg/m³ and customizable thicknesses ranging from 0.5 mm to 6.0 mm, our aerogel insulation boards deliver robust protection without adding unnecessary bulk or weight, allowing for higher energy densities and improved vehicle range.
Excellent Electrical Insulation
In addition to thermal protection, the aerogel pads provide strong electrical insulation with a surface resistance greater than 500 MΩ, safeguarding the battery system from potential short circuits and electrical failures.
Eco-Friendly and Biologically Safe
Manufactured in compliance with RoHS, REACH, and ELV standards, our aerogel pads are non-toxic, environmentally friendly, and safe for use in both passenger and commercial EVs.
