Product specifications

In the event of a fire or thermal runaway, S1 materials shield the battery enclosure or substrate by resisting high temperatures, impact and abrasion from debris, and protects against blast and pressure waves. Our S1- Series help to prevent thermal runaway in electric vehicles (among other applications) from progressing, protecting life and critical equipment.

  • Protects against temperatures of over 1300 °C
  • Capable of being fitted to acute angles, S1 materials are ideal for complex geometric shapes
  • Lightweight - an important trait for increasing the range and performance of a battery pack
  • Low smoke and toxicity during a fire
  • Flexible and less than 1 mm thick, S1 materials offer advanced protection without intruding into vent space
  • Its unique properties mean that, unlike intumescents, our S1- Series stay the same thickness throughout a fire event.

Tested for use in the toughest conditions

Variation in thermal runaway

The extent of our testing allows AIS to characterise different vent behaviours. our S1- Series provides the highest performance, offering protection against both intense jet fire scenarios, and sustained energy releases.

The result of 250+ tests

AIS tests different cell formats, energy densities, chemistries, and vent spaces. These include some of the world's most reputable cell brands, such as CATL, SVOLT, and CALB among others.
