Normally when we say the length of the airbag, we mean the Effective Length

1). Outer Rubber
The outer rubber layer that covers the outside of launching airbags protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black.

2). Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
(To know the detailed technology parameter, please refer Material Selection. )

3). End Fittings
End fittings include air tightness swivel and airbags safety air inlet.


NanHai-Marine Airbag is to be constructed of an outer rubber layer, one or more Synthetic-Tyre-Cord layers, and an inner rubber layer.
The arrangement of Synthetic-Tyre-Cord reinforcement layers is showed below. All materials shall be vulcanized firmly.
