Description of Rubber Inflatable Airbags:

Rubber Inflatable Airbag is a kind of production of processed polymeric materials. It is formed by two layers of synthetic rubber and one layer of high-tenacity synthetic fibre fabric in the middle as compression stress structure; it is vulcanized as various sizes and shapes of pressure-proof Rubber Inflatable Airbags.

Application of Rubber Inflatable Airbags:

It can substitute the wooden or steel mandrel used for pouring the hollow of large reinforced concrete structure. It is widely used in bridge construction, irrigation works and tunnels.

Features of Rubber Inflatable Airbags:

High compression strengthHigh elasticityStrong air tightnessUsed repeatedly for many timesLower cost
