Product Specification
Extover® for the transport of hazardous goods
Extover® offers safe fire and leak protection for the packaging and transport of hazardous materials, e.g. electrolyte. It is ideally suited as a packaging material for the loose filling of outer packaging and for the filling of fireproof packaging.
- Very good fluid retention
- Acid and alkali resistant
- Minimal weight (low dumping costs of contaminated material)
- Minimal thermal conduction
- Unlimited self-life
- Causes no extinguishing agent damage (compared to water, foam or powder)
- Causes no corrosion (compared to extinguishing salts)
- Can be used with other fire extinguishing agents
- Environmentally and health friendly (pure glass)
- Non-hazardous, no danger to users (e.g. due to extinguishing gases or oxygen reduction)
- Reusable (if not contaminated)
The use of expanded glass beads as inert, non-combustible, nonconductive lining material complies with the ADR regulations and the packaging instructions P908, P909, P910, P911, LP904 and LP906.
