Pontoon Airbags
SunHelm Marine manufactures high-performance marine buoyancy solutions from durable, high-strength composite materials, delivering exceptional corrosion resistance, impact resistance, and load-bearing capacity for demanding offshore operations like ship repair, salvage, and marine construction. Crucially, their products are cold-resistant, maintaining critical flexibility in extreme low-temperature waters (e.g., Russia, Northern Europe, Canada) to absorb ship impact energy, reduce hull stress, and ensure safe buffering during vessel movement and docking.
Since September 29, 2025, SunHelm has commenced production of EUDR-compliant marine airbags , becoming the first enterprise in China's industry to support this green initiative.

Pontoon Airbag Characteristics
- The rubber cylinder is flexible, allowing for a vacuum state and easy folding. It occupies minimal space, is lightweight, and facilitates transportation.
- With a material density of around 1.3, the float's weight in water is significantly lighter than in air, making it convenient for underwater installation.
- High overall buoyancy efficiency results in low unit buoyancy costs, providing the float with a competitive advantage in terms of unit buoyancy costs.
- Add cold-resistant materials, optimize rubber formula, and improve low-temperature performance.
- The operating temperature range is extended from -35°C to -50°C, enabling stable operation in extremely cold environments.
- Meet customers' needs for use in extremely low temperature environments and provide more reliable product solutions.
- The heavy-duty pneumatic float, with a net sleeve, enables force transmission at mooring points.
- It boasts a rational structure, easy installation, and reliable performance.
- The float has an inflation control device for leak prevention, automatic air release, emergency release, and valve protection, ensuring internal pressure safety.
Buoyancy Cases
These products are widely used in marine engineering, salvage operations, and heavy equipment handling. With core advantages such as high load capacity, rapid inflation/deflation, and corrosion-resistant materials, they provide safe and reliable buoyancy support for water-based operations.
