Sealing solutions for alternative fuels
FiPur® 110 - the sealing material for lower temperatures
Alternative fuels are becoming more important to achieve the goal of a co2-neutral economy. High-tech gas applications require powerfull solutions. For this reason, the Fietz Group has developed FiPur® 110, a low-temperature polyurethane.
FiPur® 110 high-performance polyurethane guarantees a secure sealing solution, even under the harshest conditions.
Requirements
• Tough and gastight seals for valves and couplings
• Pressure: LPG 14 bar, CNG 250 bar, up to 700 bar for hydrogen
• Temperature: -50° to 80°C
• Resistant against hydrogen, CNG and LPG
• Low permeability
• Lifecycle: >10,000 h
Common design: O-Ring with Back-up Ring
Disadvantages
• Larger installation space for combination with Back-up Ring
• Higher permeability of gas through the use of elastomers
• Latent risk of fault caused by explosive decompression
• Mechanical damages caused by coupling processes
New solutions: Robust FiPur® O-Ring or Formed Part,
tailor made low-temperature TPU (TR10-50°C)
User benefit
• Reliable and durable sealing solution
• Outstanding flexibility at low temperatures
