CellBlockEX Applications

A fire protection concept should be tailored precisely to the needs and local conditions. Hazards during operation, production, transportation, storage, recycling or disposal are taken into account. CellBlockEX as a multi-functional fire extinguishing agent offers a solution for numerous applications and avoids problems with regards to the extinguishing effect, as well as the protection of assets and the environment. CellBlockEX is suitable for class A, B, D and K fire loads in preventive fire protection or as an extinguishing agent. The reusable product effectively extinguishes fires without causing further damage.

All around extinguishing

All-Round Extinguishing Agent

The granulate is very well suited for use in industrial facilities, production operations, data processing centers, archives, warehousing and transportation. Since it is an electrical insulator, CellBlockEX is also ideal for use in the energy storage and supply sector (i.e., transformer station protection). CellBlockEX has a low dust content, tolerates frost and is easily removable.

Lithium-ion Fires

Lithium-Ion Battery Fire Protection

The increasing demand for battery cells also results in higher fire protection requirements during production, transportation, storage and the disposal or recycling of lithium-ion batteries. CellBlockEX is ideal as a dry extinguishing agent and especially well suited for processes where the use of extinguishing water or foam is not possible (i.e., the aging of lithium-ion batteries).

Safer transport lithium-ion

Dangerous Goods Packaging

Transporting freight via road, air or sea – anyone shipping dangerous goods has to observe numerous regulations. Transporting damaged or defective lithium-ion batteries is problematic and special measures are required. CellBlockEX meets the fundamental requirements for fire protection filler. Accordingly, it may be used for conforming special transport containers and it exceeds DOT requirements for lithium-ion battery transport.

Fire Prevention

Fire Prevention with CellBlockEX

Preventive fire protection encompasses steps taken in advance to counteract the outbreak and spread of fires, and to limit their impact as much as possible. In technical fire protection, CellBlockEX can be used as a fire suppressing material by permanently filling cavities, suspended ceilings, cable shafts, lines and pipes.

Dangerous goods packing

CellBlockEX as a Packaging Filler

CellBlockEX fillers protect packaged goods against damage, vibration and impact. It is lightweight, binds liquids, and is environmentally friendly. For shipping hazardous liquids (i.e., laboratory chemicals, bases, acids, paint thinner, or similar) transportation in a dangerous goods unit with a non-combustible filler/binding agent to prevent leaks is prescribed. CellBlockEX offers secure fire and leak protection when used as a packing filler for transporting dangerous substances.


CellBlockEX Used in Conjunction with CellBlock for the Transport of Hazardous Goods.

CellBlockEX used in shipping and storage containers offers fire and leak protection for the safe transport of hazardous materials. It is an ideal loose-fill fireproof outer packing.

  • Very good fluid retention
  • Acid and alkali resistant
  • 100% inorganic, pure glass
  • Inert, minimally reactive
  • Minimal weight (low dumping costs of  contaminated materials)
  • Minimal thermal conduction
  • Sound-absorbent
  • Non-perishable
  • Bacteria and germ-free

The use of expanded glass pellets as an inert filler is in accordance with the specifications of the Federal Institute for Materials Research and Testing for the transport of damaged lithium-ion batteries.*
