LUHANG marine rubber airbags are commonly used for projects in the heavy industry and marine shipbuilding sector.
Some of their most common uses are as follows:
The usage of marine airbags are especially common in the shipbuilding space. However, there has been a misconception in the product, as well as large differences in pricing available in the market. In fact, many of the suppliers claim they are providing xx amount of layers, xx amount of weight etc to justify that their product quality is the same as many of the trusted manufacturers’ products. The vast differences in prices manage to confuse many of these airbag buyers. So, what are the “promises” usually made that a buyer should be careful of?

Ideally, airbags should be made of new rubber material that adheres to the following standards:
The keyword here is new.LUHANG NEVER uses recycled or reclaimed rubber material in airbag production. This is a huge red flag. Quality rubber makes the foundation of the whole “inflatable roller” idea, especially when it has to bear very high values of weight on top. Recycled and reclaimed rubber have substantially lower elasticity and has a very fast ageing rate which compromises the integrity of airbags. Use these recycled rubber airbags a couple of times and you will realise they burst very easily.
On the other hand, cords play a big role, too. These “two cords” are supposed to be two-strand cords with more than 205 N strength per cord. Some manufacturers, like LUHANG, procure and use a higher strength cord (above required standard) to ensure quality strength; but some other suppliers use two-strand cords with lower strength sometimes. There is also the difference with other cords like dacron cords etc. The difference in use of raw materials can have a cost difference of more than 65%!!
It is not uncommon to hear certain suppliers claim something along the lines of “Our rubber airbag of this size weighs xx kg, it proves that our materials are of good quality and we give you more bang for your buck!” or when the weight info is more than a competitor, they claim that their airbags “have more materials in it so it is better!”. However, one should really understand what’s in an airbag, and how weight is affected. And by understanding more, you will see why this is a huge misconception.
Ship-launching airbags are made from rubber and strengthened by cords to provide sufficient bearing capacity. In the act of confusing buyers, some manufacturers actually have more unwanted foreign materials in the rubber sheets, which actually makes them heavier. Rubber is relatively less dense. The availability of more foreign substances in rubber will make them much heavier, but at what cost? It will substantially decrease the elasticity (which means it will fail much sooner after a couple of uses). Some even speed up aging of the rubber and massively decrease its usage safety.
Not all of them do this on purpose, though. Some have these added unneeded foreign materials in the rubber sheets due to dirty working environment or poor quality control procedures. Yet, an overly-aggressive salesperson sometimes mislead and even turn this “higher weight” info into a ‘good’ point to convince buyers. That is why in our facility, we ensure a clean working environment and set-up strict procedures to curb this issue. Only those materials intended to go into a quality marine airbag, goes into them.
LUHANG Marine Rubber Airbag Working pressure
LUHANG Marine airbag production line
We buy raw material natural rubber(from Thailand,Vietnam,Yunnan), carbon black, SBR,etc.Then Mix them as the rates(which can make sure the performance of airbags and fenders),after machine mixing and calendering,then we can see the fabric rubber layer and rubber plate.Now the workers can use them to produce the airbags and fenders. After then,we send the products to the vulcanizer to finished vulcanization.Then we will inflate the products to check the air leakage.If no problem we will packing them to pallets,waiting to ship to u.
