Product Description:
Marine Airbags have the best designed structure which consists of five different functional membranes in rubber layers.And they are made by patented whole enlacing technology which eliminates joints of cylindrical bodys with hemispherical heads.

Outer and Inner Rubber Layer
The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces.This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
The inner rubber layer seals pressurized air inside airbags.
·End Fittings
End fittings include Air Tightness swivel and Safety Air Inlet.
"These end fittings are enclosed when airbags leave our factory,
Synthetic-tire-cord layer for rainforcement
The reinforcement cord layers,which are made of
synthetic-tire-cord commonly used in tires,are
arranged atideal angles to hold the internal pressure
and distribute stress evenly.So they can provide
strong efficient reinforcement.

Technical Parameters:
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.
