Product details and specifications
Product Features
- Opening at high temperatures allowing fireman to flood the battery without additional equipment
- Fire and heat proofness of battery holes > 5 minutes at 500 °C (open flame)
- Reliable corrosion protection and sealing against water ingress
- Excellent puncture resistance
- Secure adhesion to steel, aluminum, plastics, painted substrates, and reinforced plastic substrates in automotive lightweight constructions
Application Fields
During battery assembly tesa® 54485 Fireman Access is applied to the inside of the battery housing. Whilst normal operation it securly seals the fireman access hole against water and dust. In case of fire in the battery pack the hole covering patch reliably shields the passenger compartment from fire and heat of the cells for 5 minutes. During fire in the pack (after 5 minutes) or the vehicle tesa® 54485 opens at high temperatures and ensures easy access for the fireman to flood the battery to safely extinguish it without additional equipment.
