Major Strengths of Ship Launching Airbags:
High level of safety: Equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

7. Technical Data of Ship Launching Airbags
Initial pressure
Rated working pressure,
Pe (KPa)
Bearing capacity (kN/m)Minimum burst pressure (KPa)
1. Rated working pressure:±5%.
2. Compress deformation: ±2%.
3. Bearing capacity: one meter airbag at a deformation rate of 70%, internal pressure equivalent to the rated pressure value of Pe.
8. Material: A ship lunching airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. All material layers should be vulcanized firmly.
