Thermal and Fire Protection 

Powered by our Aerogel Technology Platform, our materials have been engineered to protect in the harshest of environments.

Placed between cells, our PyroThin™ thermal barriers provide precious minutes of protection from thermal runaway propagation. When used to line battery modules, or under the pack cover, PyroThin can help protect occupants from the hazards caused by thermal runaway, and help you meet your regulatory and mandated egress requirements.

Ultra-Thin Solutions Support Drive Range Targets

Consumer demand for increased drive range is causing OEMs to pursue ever increasing cell energy density, increased battery packing density, lower weight, and more efficient thermal management.  At the same time, more stringent regulatory and manufacturer mandated battery safety requirements are being imposed.  Our lightweight and ultra-thin PyroThin thermal and fire barrier materials can help you meet your safety goals, while supporting the customer's demand for increased drive range.

Electric Vehicle Applications

THERMAL RUNAWAY PROPAGATION BARRIER

PyroThin thermal barriers placed between pouch or prismatic cells in lithium ion battery systems can provide precious minutes of protection from an adjacent cell that is undergoing thermal runaway.

CELL-TO-CELL THERMAL RUNAWAY BARRIERS

BATTERY PACK PASSIVE FIRE PROTECTION

When used inside of the battery pack, PyroThin aerogel sheets can act as a thermal and fire barrier. They can help you meet regulatory and manufacturer mandated safety goals.

BATTERY MODULE PASSIVE FIRE PROTECTION

THERMAL MANAGEMENT AND PASSENGER COMFORT INSERTS

Thin thermal insulation for passenger comfort applications in electric vehicles and high temperature solutions for internal combustion engine exhaust and thermal management applications.

PASSENGER COMFORT ISSUES
cell-to-cell thermal runaway

Cell-to-Cell Thermal Runaway Propagation Barriers

Ultra-thin, flexible PyroThin aerogel sheets are ideal solutions for use  between LiB cells and between modules for mitigating thermal runaway propagation. The low thermal conductivity of PyroThin thermal barriers, formulated with proprietary additives, can provide vehicle OEMs, cell manufacturers, module assemblers, and EV solution providers a superior passive solution to thermal runaway.

Pack Fire Protection

Battery Module Passive Fire Protection

Combined thermal insulation and fire protection of PyroThin aerogel sheets to isolate passenger interior space from high temperatures and other hazards during thermal runaway.
