Enn Lasili Wins Jung Award Again! New PA6 Material Leads Innovation in Hydrogen Storage Bottles
In the wave of innovation in the plastic industry, Enzhali has won the Rongge Technology Innovation Award in 2025, returning with honors thanks to its outstanding R&D capabilities and innovative spirit!
This time, Enchuali successfully won the "2025 Plastics Industry - RONGGE Technology Innovation Award" and the highest honor - "Annual Innovation Team Award" for the application of new PA6 materials in the inner liner of Type IV hydrogen storage bottles. This double honor not only highlights Enchuali's leading position in technology but also injects strong momentum into the development of the new energy sector.
With the growing global demand for clean energy, hydrogen, as a highly promising new energy source, is experiencing rapid development. Type IV hydrogen storage cylinders, as key equipment for hydrogen storage, require high-performance inner liner materials. The Durethan® and Akulon® Fuel Lock PA6 materials awarded to Envia this time have redefined the performance boundaries of the inner liners of hydrogen storage cylinders at the molecular design level. This innovative material acts like an "intelligent armor," safeguarding hydrogen safety in extreme environments.
Lightweight and cost advantages
The inner liner made of Durethan® and Akulon® Fuel Lock PA6 materials can achieve a weight reduction of up to 75% compared to steel alternatives, while also lowering material costs. By reducing the weight of hydrogen storage tanks without compromising mechanical performance, it can significantly enhance energy utilization efficiency. Additionally, Enka's single-layer blow molding process allows components such as valves to be directly integrated into the inner liner, reducing production costs by 30% and providing significant economic benefits for hydrogen tank manufacturers.
Excellent barrier performance
The barrier performance of PA6 material is outstanding, being five times that of HDPE and 10%-20% higher than that of ordinary impact-resistant modified PA6 alternatives. This means that under the same requirements for permeation resistance, the inner wall of the PA6 liner can be made thinner, which not only reduces weight but also increases the volume capacity of the liner, improving hydrogen storage efficiency.
Excellent thermal stability
When the hydrogen bottle is charged and discharged rapidly, it generates a significant amount of heat, which poses a great challenge to the thermal stability of the inner liner material. PA6 has a melting point as high as 225°C, much higher than HDPE's 125°C. In environments ranging from 65°C to 85°C, PA6 exhibits excellent safety margins and thermal stability, ensuring that the hydrogen storage tank maintains its strength at high temperatures and effectively limits permeation, making it safer and more reliable than HDPE.
Good low-temperature toughness
In low-temperature environments, PA6 material still performs excellently. Even at an extreme low temperature of -40°C, it exhibits outstanding rapid filling test performance, good low-temperature impact resistance, and ductility, ensuring the safe operation and normal charging and discharging of hydrogen storage tanks in low-temperature conditions.
