Rubber balloon in concrete
We can provide various specifications of Rubber balloon in concrete according to the customers' requirements.
Description of Rubber balloon in concrete:
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 balloon in concrete:
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 balloon in concrete:
High compression strengthHigh elasticityStrong air tightnessUsed repeatedly for many timesLower costTechnical parameters of Rubber balloon in concrete:
