Product Advantage


  1. High Bearing Capacity

Inflatable rubber airbag’s main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.

Henger adopts new rubber formula and high-strength enhanced synthetic-tyre-cord layer, which improves the airbag’s bearing capacity two times more than CB/T 3795--1996 standard.

The synthetic-tyre-cord layer of Henger marine airbag adopts dipped Nylon-6 1400dtex/3-V2 tyre cord.

The strength & durability of airbag improves 20%, compared to polyester tire cord which is widely used by friendly competitors.


  1. High Kneading-resistance Capability

When the airbag is rolling under the ship bottom, it will suffer a “kneading force” from ship bottom and ground because of not uniform rolling speed, which could case problems like delamination, layer buckling, etc.

Henger improved the manufacturing technique and raw material formula to strengthen kneading-resistance capability of the airbag and avoid worse accident .

Each layers of airbag are painting with specially formulated mucilage to dissolve dust & impurities.

The specially formulated mucilage

also higher the adhesiveness among each layers to guarantee the air tightness.

While most of friendly competitors cut this process in production to save manufacturing cost.

  1. New Anti-explosion Design of End Part

The possibility of air leakage in the joint area of metal part and rubber part is also increasing as working pressure of airbag is added. After using for times under high working pressure, the airbag would burst and metal part would hurt workers.

Henger invented new anti-explosion design of the airbag end part, increasing the bonding strength and air tightness between rubber body part and end metal part. Henger airbag is working very well under higher working pressure without potential safety hazard.

  1. High strength galvanized anti-release structure

casting metal part with chemlok coating.

chemlok coating strengthens the bonding between metal part and rubber body after vulcanization.anti-release structure of the metal part makes the connection more tight.
