The maximum burst strength is achieved through the dual multiple solid ropes reinforced with arms. Tested for durability and flexibility in temperatures from -30°C to +50°C, these heavy-duty balloons feature:

• High abrasion resistance
• High energy absorption (up to 3.8 tons for F-13)
• Suitable for vessels up to 1500 tons (F-13)

The cylindrical balloons of the F series are essential for recreational vessels and are widely used by passenger ships, fishing boats, and commercial ships.
