Designed to prevent fire hazards caused by thermal runaway.

These thin sheets are crafted using TOMOEGAWA's advanced ceramic fiber papermaking technology and wet papermaking technology that incorporates inorganic powders. They are robust enough to withstand high temperature and direct flame.

Feature 1Flame Penetration Resistance

The sheets resist tearing or cracking even after being exposed to flames for a set duration, effectively preventing the spread of fire through penetration.

Feature 2Thermal Barrier

By incorporating a high ratio of inorganic fibers and powders, it is possible to reduce the temperature on the back side compared to the heated surface.

Feature 3Fireproof Quality

TOMOEGAWA’s formulation design technology enables these sheets to meet the fireproof standards equivalent to UL94 V-0.

Applications

• Ideal for preventing the spread of fire in lithium-ion batteries and similar applications during thermal runaways.
• When combined with other sheet types, they enhance both fireproofing and thermal barrier properties.
