Features of Marine Rubber Airbag

1. Long lifespan

2. Movable and reusable

3. Saving investment costs

4. Saving labor and time

​
2.2 Material

1. Choose the best quality of imported natural rubber, such as smoked sheet rubber and 3L natural rubber from Thailand and Malaysia, which has good elasticity, ageing resistance, and will not take off layer. Meanwhile, During the process of produce rubber, we using efficient stabilizer to make rubber more environmentally friendly and no cracks.

Figure 2. Synthetic-tyre-cord

1. Wrap threads that run vertically through the synthetic tyre-cord pattern.
2. Weft threads that run perpendicular to the warp threads.

3. usually produce and supply airbags in size of following as per customer’s launching requirement:

Diameter: 0.8m, 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m

Effective length: 5m-24m

Layer: 4-10 layers
