Application scenarios and casesRange Extended Fuel Tank for Electric Vehicles (European Market)
Example: BMW i3 REx extended-range electric vehicle
Solution: 0.5mm aluminium lining with flame retardant coating (800°C/5min) for 9L micro fuel tank.
Achievement:
The fuel tank system reduces weight by 3.2kg, increases range by 8%, and is ECE R110 certified.
The mass production cost has been reduced by 25%, and the annual installed capacity has exceeded 100,000 sets.
Hydrogen Fuel Storage Tank Liners (North American Market)
Example: GM's Hydrotec hydrogen fuel cell vehicle
Solution: Aluminum lining carbon fiber winding, resistant to 70MPa high-pressure hydrogen embrittlement, leakage rate <0.05NL/h.
Achievement:
With a hydrogen storage density of 5.7wt%, SAE J2579 certified, the cost is 40% lower than that of all-composites.
Diesel Fuel Tanks for Commercial Vehicles (Asia-Pacific Market)
Case: heavy-duty truck ultra-long range fuel tank
Solution: 1500mm wide coil to reduce welds, surface micro-arc oxidation (hardness ≥500HV).
Achievement:
Resistant to sand and gravel impact (ASTM D3170), extended tank life from 5 to 12 years.
The annual export volume is 500,000 sets, accounting for 60% of the Southeast Asian market.
Fuel Tanks for Hybrid Racing Cars (Global Premium Market)
Case in point: 919 Hybrid Le Mans
Solution: 0.3mm local downgauging design (strength ≥250MPa), weight reduction of 1.8kg.
Achievement:
Fuel temperatures fluctuated by ≤2°C (extreme conditions), helping the team win three consecutive championships.
The technology has been transferred to the civilian 911 Hybrid, which has been certified for track safety by TÜV SÜD.
FlexiShield 5052 redefines the standard of automotive fuel tank technology with the triple advantage of "ultra-thin, corrosion-resistant, and high-strength". From BMW hybrids to tracks, their performance has been rigorously proven. With the wave of hydrogen energy and intelligence, the material will drive the evolution of fuel systems to a zero-leakage, adaptive, and cross-media future.
