This high-quality fire extinguishing granulate is the ideal solution for the safe storage and the clean, efficient extinguishing of Lithium-Polymer (LiPo) and Lithium-Ion batteries. Whether in workshops, RC applications, e-bike service centers, or battery storage areas – with Extover®, you are perfectly equipped to handle critical lithium and metal fires.
How Extover® Works:
The expanded glass granulate is gently poured onto the fire source, encapsulating the burning material and cutting off oxygen supply. At extremely high temperatures, the material melts, spreading over the surface like a glass seal. Upon cooling, it solidifies into a crust, creating an airtight barrier that prevents re-ignition.
Tested Fire Performance:
The extinguishing effectiveness for metal fires has been tested and verified by MPA Dresden using sodium and magnesium fire trials.
Application Areas & Fire Classes:
Extover® is suitable for Class D fires (metal fires) and lithium battery fires (LiPo, Li-Ion). It helps control difficult fire loads such as burning batteries, metals, or reactive materials without causing secondary damage.
Application – In 3 Steps:
- Secure the area: Clear surroundings, maintain safe distance, wear PPE.
- Apply gently: Pour the granulate softly and generously over the fire source.
- Cover completely: Ensure a layer of 10–30 cm above the fire. Allow the area to cool, then dispose of contaminated material properly.
Key Benefits:
- Forms a protective, airtight layer through melting and solidification
- Oxygen displacement for effective suffocation of the fire
- Environmentally friendly, 100% inorganic, inert, non-reactive
- Long-lasting, maintenance-free, non-perishable
- Lightweight and low thermal conductivity
- Excellent liquid absorption, acid and alkali resistant
- Bacteria- and germ-free, sound absorbing
- Easy to integrate into existing safety concepts
Typical Applications:
- Safe storage of LiPo/Li-Ion batteries (e.g., in battery safes, transport boxes)
- Fire suppression in case of thermal runaway or metal fire
- Workshops, RC model building, e-bike/e-scooter service, test & charging stations, shipping preparation
Why Extover® Instead of Water, Sand, or ABC Powder?
