    Material and Construction of Luhang Marine Launching Air Bags


    The marine air bag wall is constructed with layers of rubbers plates. The inner layers are reinforced with nylon cord net. These layers support the airbag with bearing strength when the airbag is inflated. More layers the airbag wall has, greater strength the airbag has. And the nylon cord net plays a critical role in strength. Besides the cord reinforced layers, there is one extra layer without cord net outside the wall. This rubber layer has a function of anti-wear and anti-aging. To maximize the function of the inner layers and the exterior layer, the rubber material is specially optimized with suitable mixing formulas.
