1.Standard size of marine airbags
Diameter(D):0.8~2.0m
Effective Length(EL):6~18m
Total Length(TL):7~19.5m
2 Standard number of layer
In order to confirm airbag's safety working pressure
we define the number of layers,which means the
number of synthetic-tire-cord layers.Normally we
offer marine airbags with 4,5,6,7,8 layers.Other
types are available upon request.
3.Material type of Synthetic-tire-cord
There are two kinds of synthetic-tire-cords with different performance.Refer to following table.
