| Product List |
Ship launching airbags are specialized marine rubber air bags designed for launching marine vessels, ship landing, or haul-outs. These heavy-duty airbags are also widely used in loading, floating, lifting, and moving sunken ships, as well as salvaging stranded boats.
Constructed with synthetic-tire-cord layers between inner and outer rubber layers, these cylindrical balloons represent an innovative ship-launching technology that overcomes traditional limitations of fixed launching tracks.

| Effective Length (EL) | 1m~32m, or customized length |
| Total Length (TL) | 1.2m~35m, or customized length |
| Loading Capacity | 10 ~ 40 ton/m, or customized capacity |
| Product Technology | Holistic wrapping technology |
| Standard | ISO 14409 |
| Working Pressure | 7-500KPA |
| Lifespan | 10 years |
| Material | Synthetic-tire-cord layer |
| Certification | SGS BV CCS ABS LR |
| Layers | 4~12 layers |
Our rubber airbags feature a robust construction with an outer rubber layer, multiple synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly together. Additional layers are applied at the end shoulders for enhanced durability.
The reinforcement layer consists of rubber-coated synthetic-tire-cord fabrics twined at ideal angles using our patented Holistic Wrapping Technology. This ensures even stress distribution and optimal pressure containment.
