Innovative Air Bag For Enhanced Protection And Performance In Automotive Sector

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.
