1.5×12m Marine Rubber Airbag High Pressure Wear Resistant 8 Year Lifespan

 

Description

 

Our ship launching airbags are designed for safe and efficient vessel launching operations. Made from high-strength synthetic-tire-cord layers and natural rubber, they offer exceptional durability and resistance to pressure, abrasion, and aging. These airbags are available in standard sizes ranging from 1.2m to 2.5m in diameter and 5m to 18m in length, with custom sizes available. The multilayer structure ensures excellent load-bearing capacity, while the outer rubber layer protects against wear and environmental damage. Ideal for medium to large shipyards, these airbags simplify the launching process and reduce equipment costs.
